Combined type transformer with intelligent communication demarcation circuit breaker switch function

Abstract

The invention provides a combined type transformer with an intelligent communication demarcation circuit breaker switch function. The combined type transformer comprises a cabinet body; a high voltage chamber is arranged at the left side of the front of the cabinet body; an intelligent communication demarcation circuit breaker switch cabinet is arranged at the inner part of the high voltage chamber; a main low voltage chamber is arranged at the right side of the front of the cabinet body; a low voltage incoming cabinet is arranged at the inner part of the main low voltage chamber; a low voltage chamber is arranged at the right side of the cabinet body; an outgoing cabinet and a capacitor cabinet are arranged at the inner part of the low voltage chamber; the low voltage parts are connected through a busbar. The combined type transformer with the intelligent communication demarcation circuit breaker switch function not only has a demarcation short-circuiting function of cutting off T joint of a 10 KV main grid rapidly when a user incoming side is in fault, but also has no need to consider the factors of components and parts such as thunderstorm prevention, mildew prevention and ageing prevention while having a complete and powerful collection function of a user network, so that the combined type transformer becomes smaller and more exquisite in volume; materials are saved, and manufacturing difficulty and manufacturing cost are reduced.

Description

technical field [0001] The invention relates to the technical field of a boundary circuit breaker switchgear, in particular to a combined transformer with the switching function of an intelligent communication boundary circuit breaker. Background technique [0002] There is a possibility of failure inside the user connected to the T of the 10kV cable line. The fault sometimes occurs on the high-voltage side of the incoming line of the combined transformer used by the user, and the high-voltage side generally only has fuse protection and backup fuse protection, and there is no boundary short-circuit breaking function. Therefore, it will cause the outlet switch of the superior substation to trip over the next level. Often a user's failure will lead to a power outage of the entire transmission line, resulting in immeasurable economic losses. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a combined transformer wi...
