The invention discloses an intelligent high-voltage alternating current energy management control device, which includes a vacuum circuit breaker, a three-phase combined voltage transformer, a current transformer and a zero-sequence current transformer respectively connected to the vacuum circuit breaker; the vacuum circuit breaker It includes the mechanism box as the base, the operating mechanism fixed in the mechanism box, the linkage shaft connected to it through the mechanism output crank arm set on the operating mechanism, the support mechanism linked with the linkage shaft, and the support mechanism connected to the upper end of the support mechanism. A vacuum interrupter, an outer insulating cover covering the vacuum interrupter, and a kneeling buffer limit device connected to the linkage shaft. The present invention adopts functional unit module design, installs the current and voltage transformers on the vacuum circuit breaker, and installs the control device on the wire bar, so as to prevent the control device from being affected by the circuit, and the knee-type buffer limit device greatly improves the The closing reliability of the circuit breaker during operation improves the opening speed of the circuit breaker and reduces energy consumption.
Description
technical field technical field [0001] The invention relates to the technical field of electric power equipment, in particular to an intelligent high-voltage alternating current energy management control device. Background technique [0002] In the prior art, vacuum circuit breakers are usually used to realize the distribution and protection of power supply in the distribution network, but due to the problems of the existing design, they are not suitable for frequent operations that often occur at the end of the power grid or in some small and medium power distribution systems In some cases, faults and protection failures are prone to occur, resulting in short service life and unstable power distribution at the end, which urgently needs to be improved. Contents of the invention [0003] In order to overcome the above-mentioned problems in the prior art, the present invention provides an intelligent high-voltage alternating current energy management control device mainly ...
