AI Technical Summary

Technical Problem

The existing high-voltage switching current monitoring device cannot respond quickly and cut off the circuit when facing abnormal situations such as current overload and short circuit, resulting in the sensor being easily damaged or even burned, increasing the cost of the device's use and maintenance.

Method used

A high-voltage switching current monitoring device with self-protection function is designed. By setting up a Hall current sensor, a power-off mechanism and a driver in the protection mechanism, the current is monitored in real time and the circuit is quickly cut off when abnormal conditions are detected.

Benefits of technology

It realizes rapid response and self-protection for abnormal situations such as current overload and short circuit, avoids damage to Hall current sensors and high maintenance costs of the device, and improves the safety and reliability of the device.

Abstract

The invention relates to the technical field of current monitoring, and particularly discloses a high-voltage switch current monitoring device with a self-protection function, and the device comprises a fixed bottom plate; four mounting mechanisms are mounted on the outer surface of the fixed bottom plate, a protection mechanism is mounted at the top end of the mounting mechanism on the outermost side, and a cooling mechanism is mounted at one end of the fixed bottom plate; the protection mechanism comprises a Hall current sensor, a fixing frame, a power-off mechanism, a supporting block and a mounting hole; the connecting line is connected with the high-voltage switchgear through the plugging connector, so that the Hall current sensor can monitor current in real time, and when abnormal conditions such as current overload and short circuit are monitored, the driver quickly responds to drive the positive and negative lead screws to rotate, so that the two power-off plates are driven to move towards the middle to cut off a circuit, and the safety of the high-voltage switchgear is improved. Due to the design, the monitoring equipment has a self-protection function and can be prevented from being damaged or even burnt down, and the use and maintenance cost of the device is reduced.
