Visual breakpoint isolation switch box

Abstract

The invention particularly relates to a visual breakpoint isolation switch box, which comprises a box body, a handle arranged outside the box body, and an interlocking mechanism and a display device which are arranged in the box body. The interlocking mechanism comprises an electromagnetic lock; the electromagnetic lock further comprises a spring bolt rod; the handle is connected with a transmission rod; the transmission rod is connected with the interlocking mechanism and the display device; and a first visible window is arranged in a box door of the box body, and the first visible window isused for observing content displayed by the display device. According to the invention, a worker can clearly identify whether the visual breakpoint isolation switch box is in a switching-off state ora switching-on state; in addition, by arranging a second spring bolt hole and an electromagnetic lock corresponding to the second spring bolt hole, when the visual breakpoint isolation switch box is in a power-on state, the electromagnetic lock and the second spring bolt hole are attracted, so that a driving disc is fixed and prevented from rotating; and the handle cannot rotate, and meanwhile, the box door cannot be opened, thereby ensuring the safety of workers.

Description

Technical field [0001] The invention relates to the technical field of an isolating switch box, in particular to a visual breaking point isolating switch box. Background technique [0002] The isolating switch box plays the role of electrical isolation. When the electrical circuit needs to be repaired, the isolating switch box serves as an obvious disconnection point, so that the maintenance personnel can safely repair. [0003] As a very important component in the isolation switch box, the circuit breaker can quickly cut off the power when a short circuit or an overcurrent fault occurs in the circuit to prevent the expansion of the fault. It can also be used as a general switch to realize the distribution and control of electric energy. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, protect power lines and motors, etc., and can automatically cut off the circuit when they are seriously overloaded, short-circuited, or under-volt...

AI Technical Summary

Problems solved by technology

[0005] However, the opening and closing state of the current circuit breaker is all through the staff carefully observing from the visible window to see whether it is in the opening or closing state, which increases the safety hazard of the staff's maintenance. In addition, the current isolating switch Regardless of whether the switch box is in the power-on state or the power-off state, the isolating switch box can be closed or opened. It is easy to cause misoperation without opening and charging, which increases the safety hazard of the staff's maintenance.
