Embodiment Construction

[0021] see figure 1 In order to better understand the technical solution of the present invention, the inventors of the present invention will describe in detail below through specific embodiments in conjunction with the accompanying drawings:

[0022] see figure 1 , a reclosing circuit breaker of the present invention includes a control panel 1 and several reclosing bodies 2 . The control board 1 is provided with a plurality of circuit breaker signal input terminals 11, and the number of circuit breaker signal input terminals 11 is not less than the number of the recloser body 2, so as to facilitate the expansion of a recloser circuit breaker of the present invention. Each recloser body 2 is correspondingly connected to the corresponding circuit breaker signal input terminal 11 on the control board 1 through a data connection line.

[0023] The current signal and leakage current signal of the reclosing body 2, and the status indication signal that the reclosing body 2 is in...

Abstract

The invention discloses a reclosing circuit breaker in the field of electrical equipment. The reclosing circuit breaker comprises a control panel, a display panel and a number of reclosing bodies. Thecontrol panel is provided with circuit breaker signal input terminals, wherein the number of the circuit breaker signal input terminals is not less than the number of the reclosing bodies. Each reclosing body is correspondingly connected with a circuit breaker signal input terminal on the control panel. The control panel is provided with a voltage signal input terminal. The voltage signal input terminal is connected with each phase of power supply wire of a three-phase four-wire power supply system, so that the control panel acquires the voltage sampling signal of each phase of power supply wire of the three-phase four-wire power supply system. The control panel is provided with a bus terminal. The bus terminal is connected with the display panel. The control panel is provided with a direct current power supply input terminal connected with a direct current power supply.

Description

technical field [0001] The invention relates to a reclosing circuit breaker in the field of electrical equipment. Background technique [0002] The leakage protection switch with reclosing function is a circuit breaker with leakage protection function = reclosing function, remote communication function, etc. on the basis of ordinary molded case circuit breakers. It can meet the "four remote" functions. In rural and three-phase four-wire power supply systems where protection is required, it can protect and control lower-level equipment and personnel. [0003] With the intelligent development of electrical equipment, new requirements are put forward for the primary and secondary integration of switchgear. The traditional switchgear is equipped with both primary equipment and secondary equipment in the product design mode, which puts forward higher requirements for the design, manufacture and maintenance of each switch, and because of the overlapping functions, unnecessary was...
