Abstract

The invention provides a portable puncture device and a using method thereof, and belongs to the technical field of power equipment. The device is directly fixed on a to-be-detected capacitor througha fixing support, laser emitted by a laser emitter coincides with a preset target point on the to-be-detected capacitor by adjusting the position of a driving device, a hollow nail breaks through an element in the to-be-detected capacitor through the driving device, the hollow nail is provided with an axis through hole to guarantee the penetration of laser generated by the laser emitter and enablethe precision of the breakdown position of the hollow nail, the controller is arranged, and can excite an instruction for the action of the driving device according to a preset voltage value on the to-be-detected capacitor, so the precise control is achieved, the work efficiency is improved, and human errors and the number of times of false tests are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and in particular relates to a miniaturized portable puncturing device and a method for using the same. Background technique [0002] Internal fuses are widely used as the first internal fault protection in the design of high-voltage shunt capacitors in our country. Once a single component breaks down during the operation of the capacitor, the internal fuse connected in series with it will act to quickly isolate the faulty component. Except for a small loss of capacitance, the entire capacitor unit and even the entire capacitor bank can still operate normally. In the standard GB / T 11024.4-2019 "Shunt capacitors for AC power systems having a rated voltage above 1000V-Part 4 Internal Fuse" and IEC 60871-4-2014 "Shunt capacitors for AC power systems having a rated voltage above 1000V-Part 4Internal In "fuses", the isolation test of the internal fuse is used to assess the internal fuse us...
