Problems solved by technology

At present, the operation of changing high voltage to low voltage on the distribution box is mostly manual operation. The process is: one person operates, and two or more people monitor. This is an important safety measure written into the operating procedures, otherwise It is not allowed to operate. In this way, the operation is not only troublesome, but also the operators and guardians will be disturbed by the electromagnetic field, which will affect the physical and mental health.
[0003] Therefore, it is absolutely necessary to use remote operation. The existing remote operation is to mechanically pull the guillotine switch. In this way, the mechanical structure of the pull is complex and occupies a large area, resulting in a high failure rate and a high error rate. Inconvenient to use

Abstract

The invention relates to a button type high-voltage remote control switch for a distribution box. The technical scheme is as follows: the upper end of an opening and closing knife switch is matched with a circuit breaking and closing movable knife edge; the inner side of the opening and closing knife switch is provided with a circuit breaking spring for pushing the opening and closing knife switchaway from the circuit breaking and closing movable knife edge to realize circuit breaking, and the outer side of the upper end of the opening and closing knife switch is provided with a circuit closing actuator for pushing the opening and closing knife switch to the circuit breaking and closing movable knife edge to realize circuit conducting; the upper end of the opening and closing knife switchis matched and locked with a circuit closing pin, the circuit closing pin is moved upwards by the pressing and pushing of a circuit breaking actuator, and the opening and closing knife switch is enabled to be opened to realize circuit breaking; and the outer side of the circuit breaking actuator is provided with a circuit breaking button installer, and the outer side of the circuit closing actuator is provided with a circuit conducting button installer. The beneficial effects are that the external remote control structure can be simplified through designing the button type structure, the diversity can be realized, the structure is simple, the occupied area is small, the safety factor is greatly improved, and the fault rate is significantly reduced.

Description

technical field [0001] The invention relates to a high-voltage control switch and a method, in particular to a push-button high-voltage remote control switch for a distribution box. Background technique [0002] Electricity is the driving force of modern industry. In the process of electric power transmission, high voltage changes to low voltage is a common situation encountered by industrial and mining units. At present, the operation of changing high voltage to low voltage on the distribution box is mostly manual operation. The process is: one person operates, and two or more people monitor. This is an important safety measure written into the operating procedures, otherwise It is not allowed to operate. In this way, the operation is not only troublesome, but also the operators and guardians will be disturbed by the electromagnetic field, which will affect the physical and mental health. [0003] Therefore, it is absolutely necessary to use remote operation. The existing ...
