Detailed Description
The technical solution of the present invention will be explained in detail through the accompanying drawings.
Example 1: the comprehensive intelligent test equipment shown in fig. 1 and 2 comprises an integral cabinet, wherein the integral cabinet is divided into a test cabinet 1 and a control cabinet 2 which are arranged in parallel, an industrial personal computer 21, a Programmable Logic Controller (PLC), a human-computer interface 22 and a control assembly are arranged in the control cabinet 2, a frequency converter and 6 load motors with different powers are arranged in the test cabinet, and the powers are 1.5kw, 4.0kw, 7.5kw, 22kw, 55kw and standby load motors; the test cabinet 1 is provided with a tank chain filter station 11.
As shown in fig. 3, the control assembly comprises a load adjusting control key, a control loop emergency stop key, a 220V power inching and a 380V power inching, the control assembly is connected with the PLC, the PLC controls the on-off of the input switch and the motor contactor, the tester is connected with the industrial personal computer through the PLC, and the industrial personal computer is connected with the human-computer interface. The power grid is connected with the input end of the frequency converter through air switches QF1 and QF2, and 220V and 380V power supplies are formed between the power grid and the frequency converter respectively. The output end of the frequency converter is respectively connected with 6 load motors through a motor contactor group, and the output end of the frequency converter is connected with a test instrument.
During operation, the industrial personal computer is powered on, the human-computer interface displays a login interface, a password can be input to enter the operation interface, and a tester number, a product number and a product model are input. The 220V power supply inching and the 380V power supply inching on the operating platform can realize inching, and the risk of the fryer of directly electrifying when the frequency converter has a fault is prevented.
