Abstract

The invention provides a PT cable terminal installation structure and a PT cable wiring cabinet, the PT cable terminal installation structure comprises a circuit breaker, an isolation switch and a PT terminal, one end of the PT terminal is connected between the circuit breaker and the isolation switch, and the other end, opposite to the one end, of the PT terminal is used for being electrically connected with an external structure. In the using process, before an external circuit is switched on, the disconnecting switch can be switched off firstly, after the disconnecting switch is switched off, the connection between the PT wiring terminal and the external circuit is kept in an open circuit state, and at the moment, the external circuit is switched on, so that the problem of reverse power transmission can be effectively avoided.

Description

technical field [0001] The application belongs to the technical field of junction cabinets, and more specifically relates to a PT cable terminal installation structure and a PT cable junction cabinet. Background technique [0002] The PT cable terminal is usually installed at the end of the disconnector away from the circuit breaker. When the external line is closed during use, there will be three-phase circuits in the external line that are difficult to close at the same time. In the case where one or two phase circuits are closed first In this case, there will be a problem of reverse power transmission. Contents of the invention [0003] The purpose of the embodiment of the present application is to provide a PT cable terminal installation structure and a PT cable connection cabinet, so as to solve the technical problem of reverse power transmission existing in the PT cable terminal installation structure and the PT cable connection cabinet in the prior art. [0004] In...
