Abstract

The invention discloses an electric blocking system of a busbar sectionalizing switch, which comprises a bus, a circuit breaker and a plurality of transfer switches. The electric blocking system is characterized in that the bus is divided into a plurality of sections, the transfer switches are positioned on the bus, and one section of the plurality of the sections of the bus is provided with the circuit breaker. The electric blocking system of the busbar sectionalizing switch fully solves the problem of power failure of the bus, and effectively solves the contradiction with actual insufficient power supply; and when the bus is earthed or the sectionalizing switch is overhauled, the power of corresponding circuits does not need to be cut so as to ensure the stability and the reliability ofthe power supply of a user.

Description

Technical field [0001] The invention relates to an electrical blocking system for a switch, in particular to an electrical blocking system for a bus section switch. Background technique [0002] In the power system with two busbars and one subsection or three busbars and two subsections, there are usually two ways of operating as a backup for each other. There are two common forms: (1). Sectional standby automatic switch: two-way incoming cabinet As a normal working power supply, the section cabinet is used as a backup. When any one of the incoming switches fails and trips, the bus tie switch cabinet is automatically put into use as a backup power supply. (2) Incoming line standby automatic switching: One incoming line cabinet and section cabinet are used as normal working power supply at the same time, and the other incoming line cabinet is used as a backup. When the incoming switch fails and trips, the other incoming line cabinet is used as a backup The power is turned on auto...
