Frequency converter test platform with high safety factor

Abstract

The invention discloses a frequency converter test platform with a high safety factor and belongs to the frequency converter test field. The frequency converter test platform with a high safety factorcomprises a box body, and a test bin is fixedly mounted in the middle of the front surface of the box body in an inward concave manner; the right side of the test bin is rotationally connected with abox door through a hinge; a mounting table is fixedly mounted on the inner bottom wall of the test bin; and binding posts are fixedly installed in the test bin. A fire extinguishing nozzle is fixedlymounted on the inner top wall of the test bin; a programmable power supply is arranged in the box body; a motor is arranged at the bottom end in the box body; abnormal detection data can be transmitted to a single-chip microcomputer through a temperature sensor and a smoke sensor; the single-chip microcomputer sends a signal to an air pump, the air pump is started to generate an airflow to be blown into a dry powder storage box, the air pressure in the dry powder storage box is increased, so that dry powder is blown into a discharging pipe and sprayed out through a fire extinguishing nozzle,automatic dry powder fire extinguishing is achieved, property and personal safety is protected, and the safety coefficient is high.

Description

technical field [0001] The invention relates to the field of frequency converter testing, and more specifically relates to a frequency converter testing platform with high safety factor. Background technique [0002] The frequency converter is mainly composed of rectification (AC to DC), filter, inverter (DC to AC), braking unit, drive unit, detection unit, micro-processing unit, etc. The frequency converter is widely used, so the frequency converter needs to be tested before leaving the factory. The traditional test method for frequency converters generally adopts the manual connection test method, which is slow in speed and poor in work efficiency, resulting in increased test costs. Now the frequency converter test platform is commonly used for testing. [0003] The existing inverter test platform does not have a good safety guarantee function. When an accidental fire occurs during the inverter test process, it cannot sense and automatically extinguish the fire in time, w...

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a frequency converter test platform with a high safety factor, which has the advantages of automatic fire detection, improved safety performance, property and personal safety, and solves the problem of existing frequency converters. The test platform does not have a good safety guarantee function. When an accidental fire occurs during the inverter test process, it cannot be sensed and automatically extinguished in time, which is more dangerous and not conducive to the protection of property and personal safety.
