Electrical Test The connections of earthing insulation can ensure at the 2000V voltage for 1 minute. 5 m/s is 148–160 kPa. OSR is Oil actuated Relay. Compact & hence, low weight design with high efficiency.
In order to reduce the breaking capacity of the main contact, the value of transition resistance should be lower. If high eddy currents, local overheating, or partial discharges occur within the tank, bubbles of resultant gas rise to the top of the tank. Normally, the two relays should send alarm/trip signals at the same time or within a certain period of time (may be milliseconds). Buchholz Relay Testing Procedures The different types of Buchholz relay testing procedures include the following. This protective relay triggers the tripping circuit when the oil flow exceeds the specified limits, thus making the transformer to be turned off and contain the damager to the OLTC and Transformer. Oil Surge Relay for Transformer. Moisture content results in the dielectric strength of oil being reduced and flashover occurs. In terms of OLTC operation characteristics analysis, electromagnetic transient simulation research has been carried out for the switching process of the OLTC, and quantitative analysis has been obtained from the two aspects of amplitude and phase. A magnetically held paddle attached to the bottom float is positioned in the oil-flow stream between the conservator and transformer tank. Magnetic Oil Level Gauges - Magnetic Oil Level Gauges Indicators Manufacturer from Vadodara. Buchholz Relay And Oil Surge Relay OSR.
The following testing have to do for the transformer oil. Besides, the OLTC has a separate conservator, and the pipeline from the oil chamber to the conservator has a protective relay (oil flow velocity relay and oil pressure relay). In the process of switching, when the moving and static contacts are separated from contact, the main contact and transition contact not only rotate with their own rapid mechanism but also rotate around their own rotating shaft under the action of the spring at the bottom of the contact. Three different types of oil flow relays from the same manufacturer with speed threshold values of 1. Oil surge relay in transformer les. Why the current leads voltage in the case of a capasitor. What is Buchholz Relay?

2017) puts forward the measurement method of the on-load tap changer current during transformer operation, and models and simulates the transformer and on-load tap changer in ATP-draw. Correspondence: Zhicheng Xie, And the quantitative relationship between oil flow and oil pressure can be expressed by linear function. It can be seen that the transition resistance value has a great impact on the OLTC switching capacity. If this relay operates, do not re-energize the transformer until you have determined the exact cause. Current transformer with relay output. In view of the problem that the oil flow surge caused by tap switching of the OLTC may cause protection mis-operation, taking the typical double transition resistance type OLTC as an example, the simulation analysis and experimental demonstration of the flow rate and pressure of the insulating oil in the oil chamber during the action of the tap changer were carried out in this article. A machined surface is provided on the relay body for the purpose of testing the mounting of the relay, both in the inclined direction and at right angles to the pipe where it should be horizontal. The floats of the transformer must be check for air stiffness by, for instance, immersing them in warm oil to make a surplus force in them. The Buchholz relay diagram is shown below. 2010) proposed a modeling structure of on-load tap changer based on the arc model.
Functional Test The testing of the Buchholz relay can be done on particularly designed PLC controlled testing unit, as well as all the contact systems reply conditions will be verified. 58°, the moving contact begins to contact with the static contact. Buchholz relay is a security device which is normally used in large oil absorbed transformers. It is situated in the pipe line between the transformer and the conservator tank, so that under normal conditions it is full of oil. Jian Hao, Chongqing University, China. The active contact not only moves with the fast mechanism but also rotates around its own rotating shaft when the moving contact starts to contact with the static contact. The test principle is shown in Figure 12. Thus, this is all about Buccholz relay, working, construction, etc. C or D. C. They will also make and carry for 0. OIL SURGE RELAY (OSR) - CTR. The increased Oil flow rate beyond the safe limit through OSR will trip the Transformer and thereby safeguarding the Transformer and OLTC. The feasibility of the proposed scheme is further verified by simulating the transient characteristics of the primary side in the switching process.
A new on-load tap changer, which triggers the thyristor circuit through overvoltage and realizes the switching process of uninterrupted current has been proposed by Li (2017). This course opens up opportunities for the learners to become/excel as a Electrical Design Engineer, Construction and Planning Engineer. 1 Condition Setting of Flow Boundary. The dislocation of oil causes the higher float to shut the higher mercury switch to connect an alarm circuit. 1 Characteristics of Oil Flow Surge Before Switching and During Unburned Arc. On-load tap changer (OLTC) is one of the key components of converter transformer, which plays the role of compensating power grid voltage change and optimizing the control angle. Leakage Test The Buchholz relays can pack with oil at the 90 C temperature and at the force of bars and verified for the outflow after 30 minutes. The process from contact to separation is the opposite. Off and contain the damager to the OLTC and Transformer.

Impinge upon the flap fitted to the trip element causing it to rotate about its axis and so bring the Mercury switch to the closed position, which in turn operates the tripping devices. The Buchholz Relay is one of the most essential protective devices to protect equipment such as transformer, capacitors, on-load tap changers, etc. 5 m/s) are revealed. Since the gasification of transformer oil caused by arcing is not considered in the simulation, the actual oil flow velocity should be higher than that of the numerical simulation, so it is necessary to consider increasing the setting value of oil flow relay.
This article focuses on the key operation problems of an OLTC, that is, how to optimize the threshold of oil flow relay and oil pressure relay to ensure the correct action of protection, thus, the refined modeling, oil flow characteristic analysis, and protection threshold optimization are not only the difference between this article and the existing literature but also the key technical innovation of this article. It is a kind of oil and gas activated security relay. Silica gel Dehydrating Breather: The silica-type breather is used for drying the air drawn into the oil conservator when they drop in load and temperature causes the oil to contract. The environment and harshness of the fault will determine without separating apart from the transformer by checking the air samples. Fan, R., Fu, P., Tao, J., Gao, G., Song, Z., Huang, L., et al. Now d company asks in d interview d reason 4 my shud b d probable answers 4 that which may not put a negative impression. If the oil flow relay of the converter transformer OLTC is one of the above three oil flow relays, the pressure threshold of the matched oil pressure relay can be set with reference to the above results.
IEEE Access 7, 84803–84816. Features: - High material strength. Responds to excessive oil flow in the direction of the conservator and generates a signal disconnecting the onload tap changer and the transformer. If oil flow occurs from the OLTC head to the oil conservator, the flow vane switches the reed, the circuit breakers are tripped and the transformer is de-energized. Additional Information: Item Code: SO-4. It is fixed with flanged ends that make it easier to install it within oil pipes. It can be seen from Table 4 that different switching times lead to differences in arc energy, but the oil flow speed and oil pressure increase with the increase of arc energy. 128 W/(mK), and the specific heat capacity at constant pressure is 1. Oil Level Monitoring: The oil level must be monitored, a breakdown of the insulation occurs if the oil level gets too low. Conflict of Interest.
In addition, an equivalent experimental platform is built to carry out the static action characteristic experiment of OLTC oil flow relay, the corresponding relationship between the change range of oil pressure at the top of the chamber, and the oil velocity under typical value (1.
