Fan, R., Fu, P., Tao, J., Gao, G., Song, Z., Huang, L., et al. C) Variation curve of oil flow and oil pressure with total arc energy. Transformer Oil Surge Relay is a protection device for On Load Tap Changers used in Transformers. As gas builds up inside the chamber, it displaces the oil, which decreases the oil level. The complete tap changing process is shown in Figure 2, which includes two arc extinguishing processes (in step d and step f, respectively), and the breaking current, recovery voltage, and switching capacity of the two arc extinguishing processes are shown in Table 1. OSR is fitted with special Reed switch which assures rust free.
Oil Surge Relay In Transformer Panel
Oil Surge Relay In Transformer Plug
This unit functions by triggering the tripping circuit in the case when oil flow exceeds the specific levels. The Mercury switches were connected to sensitive detecting equipment and no maloperations were recorded. We have manufacturing facilities in two cities and dozens of global distributors and warehouses with whom we can ship to any country in the world. It is fixed with flanged ends that make it easier to install it within oil pipes. 413 rad/s; in the contact stage, when the fast mechanism of the transition contact rotates by 1°, the moving contact rotates by 2° around its own rotating shaft.
Oil Filled Current Transformer
Offered range is used to protect the malfunction developed inside the on load tap changer. Therefore, the calculation area is set to be filled with transformer oil (#25), with oil pressure of 100 kP A and oil temperature of 40°C. Logistic Partners Estimate Shipping Cost. Our provided valve is used to control the flow of oil from transformer to radiator. A volt-ohmmeter may also be used to check the switches. Similarly, assuming that the moving contact rotates at a uniform speed around its own rotating shaft, it has been determined during modeling that when the fast mechanism rotates 1°, the moving contact rotates 4. The relay should be mounted in the connecting pipe between the transformer and the conservator tank.
Oil Surge Relay In Transformer Calculator
Both cylinders are jointed and free to rotate about the same axis, the amount of rotation being. Buchholz Relays | Mercury Switch Type Relays. The offered range is sourced from trusted vendors of the market who use best quality material in the manufacturing process. All OSR Tested to ensure zero leakage. Precautions for Buchholz Relay Installation The conductor connection must have a paper connection while contacting the terminals instead of rubber because it may damage by the coil. During tap changing, the insulating oil in the chamber will be heated, expanded, and surged by the energy generated from arc breaking. However, these studies were carried out on the basis of experiments, and the research conclusions have certain limitations. On some relays, a rod is provided so that you can test both bottom and top sections by pushing the floats down until the trip points are activated.

2 Setting of Contact Speed. Citation: Zhou H, Xie Z, Chen X, Guan Q, Deng J, Liu G and Yan X (2022) Study on Oil Flow Surging and Protection Optimization for on Load Tap Changer of Converter Transformer. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. Among them, the maximum volume grid scale of the computational domain is 24 mm; since the gap between the moving and stationary contacts is only 1 mm at the beginning and end of the switching process, the grid scale of the corresponding moving and stationary contact surface is set to 0. In this article, in Section 2, the mathematical simulation model of OLTC is established; in Section 3, the simulation result is analyzed, and besides the experimental method, the result is proposed; the change law of the oil speed and oil pressure at the top of the chamber when the OLTC operating under different transition resistances is analyzed, so as to provide guidance for the OLTC protection configuration. The least operating time of the Buchholz relay is 0. B) Velocity field and pressure field before arcing. 3 Setting of Arcing Time, Arcing Position, and Released Energy. 2021) built a short-circuit arcing test platform and carried out the short-circuit arcing test, and put forward a proposal for the standardized configuration of on-load tap changer nonelectric protection device. Seo, J., Ma, H., and Saha, T. K. On Savitzky-Golay Filtering for Online Condition Monitoring of Transformer On-Load Tap Changer. Hence, throughout small faults, the lower float will not be changed. Therefore, the connecting rod mechanism is removed during the modeling, The motion equation of the main contact, the transition contact and the fast mechanism are comprehensively determined according to the contact structure of the dynamic and static contacts, the structure of the fast mechanisms, and the current change law in the switching process, such that it can simulate the motion of the moving contact and its fast mechanism in the switching process. OSR relay is actuated when the flow rate of oil exceeds the preset value. 5 m/s) are 96–102 kPa, 118–126 kPa, and 148–160 kPa, respectively.
Oil Surge Relay In Transformer Oil
Body is made of single piece Die cast Aluminium alloy. OSR mounted in the Pipeline connecting Conservator and On-load tap-changer (OLTC). The action pressure range and action percentage are shown in Table 5. OSR should be installed between the OLTC diverter champer & OLTC conservator champer. 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. As you know, earth leakage current is a kind of AC. The float is located slightly below the top of the pipe so that once the top chamber is filled, additional gas goes into the pipe and continues up to the conservator. Select different T1, T2, and T3 to simulate the changes of oil flow speed and pressure in the oil chamber of the transfer switch when the on-load tap changer is switched under various combinations, as shown in Table 4. The quantitative mechanism research is insufficient, so it has not formed a unified conclusion. The range serves in a different principle. Generally, Buchholtz relay connected to the main tank contains two floats i. e. upper and lower, electrically connected to alarm and trip circuits. The viscosity coefficient formula is. Any malfunction builds pressure which leads to increased oil flow. Main Domestic Market.
Buchholz Relay Construction The Buchholz Relay consists of two elements, namely the upper element, and the lower element. It's seems like you are on slow network. This relay also serves a third function, similar to the sudden pressure relay. When a slight or incipient fault occurs within the transformer, the gas generated will collect in the top of the relay housing. 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. The bottom float and switching cannot be tested with air pressure. The top float descends with the oil level until it passes a magnetic switch, which activates an alarm. Working Principle of Buchholz Relay This means lowering the location of the float and thus rolling the mercury switch.
