With the development of society, people have increasingly high requirements for the safety and reliability of electricity use. High voltage circuit breakers play a dual role in control and protection in the power system, and their performance directly affects the safe operation of the power system. Mechanical characteristic parameters are one of the important parameters for judging the performance of circuit breakers.

The high-voltage switch characteristic tester launched by Yangzhou Topu Electric Technology Co., Ltd. is designed based on the power industry standard "General Technical Conditions for High Voltage Testing Equipment" Part 3, DL/T 846.3-2004 High Voltage Switch Comprehensive Tester. This instrument provides convenience for dynamic analysis of various circuit breakers and can detect SF6 switches, GIS combination devices, vacuum switches, oil switches, column switches, contactors, etc. Built in fast micro printer, capable of printing test data and graphs.

Features

1. Product performance

(1) Time: The inherent opening and closing time of 12 fracture surfaces, in phase synchronization and phase synchronization.

(2) Recloser: opening closing, opening closing, opening closing opening of each break; Gold short time, no current interval time value.

(3) Bounce: the closing bounce time, bounce frequency, bounce process, and bounce waveform of each fracture; The rebound amplitude of each break.

(4) Speed: just in and out speed, high speed, time stroke characteristic curve.

(5) Travel: total travel, opening distance, overtravel, overshoot travel, rebound amplitude.

(6) Current: The opening and closing current values and waveform of the opening and closing coils.

(7) Action voltage: The machine provides a DC0-270V/20A digital adjustable circuit breaker action power supply, which automatically completes the high and low voltage action tests of the circuit breaker, measures and prints the action voltage value of the circuit breaker.

2. Product Features

(1) The instrument is suitable for SF6 switches, GIS composite appliances, vacuum switches, oil switches, column switches, contactors, and other commonly used metal contacts produced domestically and internationally.

(2) Sensors: Linear travel sensors and rotational speed sensors are easy and simple to install.

(3) Trigger methods: internal trigger, external trigger, sensor trigger, and manual trigger. Manual triggering can perform characteristic tests on manually opened and closed circuit breakers (without opening and closing coils), such as manual opening and closing switches on poles. Sensor triggering is mainly used in places with special requirements such as switch factories.

(4) Energy storage output: The instrument can provide a DC adjustable energy storage power supply, which can control the motor energy storage at any time without reversing the wire after one-time connection.

(5) Host large screen, wide temperature backlit LCD, contrast electronic adjustment. Complete Chinese menu prompts for operation, with one switch action displaying all data and waveform diagrams.

(6) The host can store 1000 sets of on-site opening and closing test results, with a real-time clock inside for easy archiving and storage of test dates and times; The USB interface is used for data transfer and program upgrade.

(7) The instrument has powerful data analysis capabilities and can effectively analyze various indicators and parameters of the mechanical characteristics of circuit breakers. Built in fast micro printer to print test data and graphs.
