Portable permanent magnet switch driving module with over-current protection and charging management

Abstract

The invention provides a portable permanent magnet switch driving module with over-current protection and charging management, and belongs to the field of switching equipment driving in the power industry. The portable permanent magnet switch driving module comprises a CPU, a closing and short-circuit protection driving module and a power supply module which are connected with the CPU, a bridge loop which is driven by the closing and short-circuit protection driving module, and a short-circuit protection module which is arranged on the bridge loop and connected with the CPU. The short-circuitprotection module is used for judging whether the circuit is short-circuited or not according to the size of a load before the load is connected to work. The portable permanent magnet switch driving module has the advantages that whether the coil side is short-circuited or not can be detected in time and damage to an internal loop due to short circuit is prevented.

Description

Technical field [0001] The invention relates to a switch device drive in the power industry, in particular to a portable permanent magnet switch drive module with overcurrent protection and charging management. Background technique [0002] In actual use, the existing permanent magnet switch cannot rely on traditional mechanical tools for closing operations, but must rely on a permanent magnet switch drive module for driving. When the on-site switch is actually powered off or inspected before it is put into operation, since there is no power supply, the drive module supporting the switch cannot be used directly. Therefore, it is necessary to use a portable permanent magnet drive module with battery power for operation. The existing permanent magnet drive module is not only large in size, heavy in weight, and inconvenient to carry, but it is also prone to short-circuit on the coil side and cause damage in the harsh operating environment on site. [0003] Therefore, the above model...

AI Technical Summary

Problems solved by technology

[0004] 1. The module is not only bulky, but also heavy;

[0005] 2. When the coil side is short-circuited, it is easy to burn out the internal circuit;

[0006] 3. The operating voltage cannot be adjusted;

[0007] 4. Charging requires a special AC220V plug;

[0008] 5. After the internal circuit is damaged, it cannot be found by self-inspection in time
