Description de produit
OEM 12KV Capacitive Voltage Detector Metering Circuit Breaker Transformer
OEM/ODM 10KV/12KV Phase Sequence Metering Transformer used in ring grid cabinets, circuit breakers
Introduction
Capacitive voltage metering and protection transformer is an electronic transformer designed according to the principle of capacitance dividing voltage, which is widely used in complete sets of equipment such as switches on 12KV columns, ring grid cabinets, circuit breakers, etc., to be used as a function of phase sequence voltage measurement.
Electrical Parameters
  • 8~12KV voltage time-varying ratio accuracy: 3P
  • Phase sequence voltage ratio rating: 10/√3 KV /3.25/√3 V
  • 8~12KV voltage time-varying ratio accuracy: 0.5
  • Environmental withstand temperature: -40 °C ~ +70 °C
  • Rated frequency: 50HZ
  • Rated load: 5.1MΏ
  • System rated voltage: 10KV/12KV
  • Partial discharge: 5PC
  • Withstand voltage: 42KV AC for two minutes
  • Lightning shock: 75KV 15 times each
  • Power frequency: 48KV/1min
Electrical Principles
  1. This series of products is based on the principle of capacitive voltage division. A group of capacitors are implanted in each transformer at the same time, and the transformer is used for measuring
  2. Combine the three transformers together as a three-phase metering function
  3. As shown in the product circuit diagram, Ua, Ub, Uc are three-phase measurement, the low-voltage capacitor has been built in the transformer, and the external signal output can be directly connected (two-core shielded wire, one core is grounding, and the other is signal output)

Company Overview

Xian Xiwuer Electronic & Info. Co., Ltd. is located in Beiguan, Xi'an city covering an area of 4000 ㎡, with employees of 2300, and about 580 technicians, among them, there are 135 engineers, 21 senior engineers. The company has total assets of 315 million RMB Yuan, fixed assets of 137 million RMB Yuan, which is a large enterprise mainly engaged in producing electronic components.

The company has the largest production scale of Varistor, SPD (Surge Protective Device) and HV Ceramic Capacitor in China, with the following main products:

  • Varistors & SPD
  • HV Ceramic Capacitor
  • Capacitive Voltage Divider
  • Thermistor

The main production line and inspection equipment & instrument are imported from Japan, America, Belgium and Switzerland etc. The annual production capacity of the two leading products has been reached to 5 million pcs and 150 million pcs respectively, with the market holding rate in China of about 10% and 30% respectively by continually technical innovation.

Varistors and SPD produced by the company enjoyed great reputation in the international market, being exported to many countries and areas such as Japan, USA, Hong Kong etc., with the customers like India and GE in USA. are already sold to LG company in Korea with large quantity, and also to Spain and India etc.

Not only the products quality and technical capacity, but also the completeness of the models are all in the leading place in China. The main products have got CCEE, UL, VDE & TUV approval. The quality system was set up according to the requirement of ISO9000 since 1992, and has passed ISO9002 approval by DNV International Organization in July 1994, then got ISO9001 certification by British organization in 2000, by then we are both the first one who are approved by ISO9000 certification in the North-west area of China and the same occupation. We passed all the successive periodical audit and smoothly get the new certificate registered in Holland in Aug.1997; the quality system is strengthened and completed constantly. And we also got ISO18000 certificate.

We believe we are able to supply satisfied goods and service to customers home and abroad with the most reasonable price and the shortest delivery time, on basis of our excellent quality assurance capacity, technical development capacity and rich manufacturing experiences.
