1. The 24-hour on-line monitoring function
domestic VCB on-line detection technology mostly stays in the concept research stage, and mature procts rarely appear in the market. Through the cooperation and development with foreign manufacturers, this proct uses electrode type microwave antenna sensor to capture the special feedback signal when the vacuum degree is abnormal under the normal operation state of the vacuum circuit breaker, so there is no need for power failure maintenance, which truly realizes the VCB online monitoring function< High reliability
this proct uses ultra micro power transmitter, precision resistor, capacitor and high bandwidth, high-speed operational amplifier to form emission, acquisition, isolation, filtering and amplification. The software adopts reliable measures to avoid the magnetic field, electric field, arc and other interference signals in the installation site of high voltage switch, and realizes the on-line monitoring of VCB, with high reliability, simple maintenance and self checking function in operation. It can rece the time and frequency of VCB power outage and bring direct economic benefits. Compared with the off-line detection equipment of vacuum circuit breaker, which is widely used in the market, the price is lower, which makes it possible to promote the on-line monitoring of vacuum circuit breaker< The minimum size of this series of procts is 170mm in length, 120mm in width, 65mm in height, and the weight is only 0.6kg, which is small and easy to install
the antenna sensor and VCB are installed in a non-contact way, so there is no need to change the existing condition of VCB in operation. It is suitable for installing on-line monitoring function on VCB in operation, and it is also suitable for cooperating with vacuum circuit breaker manufacturers to form a vacuum circuit breaker with on-line monitoring function< At present, the development of high-voltage vacuum circuit breakers in China is rapid, but there is almost no application in the field of on-line monitoring of high-voltage vacuum circuit breakers. The principle of on-line monitoring system of vacuum circuit breaker based on Contactless microwave emission feedback detection is simple, effective and reliable. Compared with the principle of capacitive coupling detection of intermediate shield level, it does not need to adjust the detection reference level and is not affected by voltage level and installation environment. For the vacuum circuit breaker with higher voltage level, the discharge point range of vacuum leakage is closer to the critical vacuum 10-2Pa, and the detection accuracy level is higher.
