Remote opening and closing device for circuit breakers in row and working method thereof

Abstract

The present invention discloses a remote opening and closing device for circuit breakers in row and a working method thereof. The device comprises: a first linear guide rail and a second linear guiderail are disposed in parallel along with direction in which the circuit breakers are arranged in a row; the first linear guide rail and the second linear guide rail are disposed above an end surface of the circuit breakers with a switch, and projection of the two linear guide rails on the end surface is distributed on both sides of the switch. The device has a function of remote communication, andcan realize remote automatic opening and closing control of any one of the circuit breakers in the row, without affecting realization of manual opening and closing.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a remote opening and closing device and working method for a row of circuit breakers. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the development of society and the improvement of people's living standards, there are more and more electrical equipment with multiple functions in daily office and life. The increase of electrical equipment has greatly increased the potential safety hazards of electrical lines, and put forward higher requirements for the timely opening and power-off of electrical equipment. [0004] The inventor found that there are new intelligent air circuit breakers with automatic closing on the market, and the automatic reclosing protector (smart electric operation) can realize opening and closing, but it is ...

AI Technical Summary

Problems solved by technology

[0005] 1. The current automatic opening and closing devices are all installed on both sides of the circuit breaker, limited by the space of the original distribution box, and there is a problem of limited installation space;

[0006] 2. The circuit breakers in the original distribution box are arranged in rows, and the gap between adjacent circuit breakers is very small. In order to realize the automatic opening and closing transformation of each circuit breaker, it is necessary to adjust the setting position of the circuit breaker Make adjustments so that both sides of each circuit breaker have a certain installation space; this will cause the problem that the original cable length is not enough, resulting in long construction period, complicated construction process and high construction cost

[0007] 3. In the existing process of opening and closing the circuit breaker for the distribution box, the power setting must be powered off before the transformation can be carried out, which affects the normal power consumption of users

[0008] 4. During the opening and closing process, the force on the opening and closing handle of the circuit breaker is uneven, which may easily lead to misoperation or improper operation, and bring potential safety hazards

[0009] 5. The current opening and closing device can only correspond to one opening and closing device for one circuit breaker. When opening and closing a row of circuit breakers, these opening and closing devices cannot directly open and close the existing row of circuit breakers. Instead of gate renovation, it is necessary to change the layout of circuit breakers, which may easily lead to problems such as insufficient installation space and insufficient length of original cables.
