IEC60898-1 Circuit Breaker Mechanical And Electrical Life Testing Machine
Products Description
IEC60898-1 Circuit Breaker Mechanical And Electrical Life Testing Machine
Product information:
It conforms to standards:GB10963.1-2020 clause 9.11
IEC60898-1:2015 clause 9.11, SLS 1175:2021
Application
It is used to conduct mechanical and electrical life tests on miniature molded case circuit breakers to assess whether the circuit breaker will experience excessive wear after 4,000 operating cycles, the position of the moving contact is inconsistent with the corresponding position of the indicating device, and the casing is damaged enough to be tested. Access to live parts, loose electrical and mechanical connections, leakage of sealing compounds, etc. to determine compliance with the standard.
Technical parameters:
1. The equipment box adopts the overall high-quality steel integrated chassis, spraying the sealing plate, and the surface is anti-static, anti-rust and anti-corrosion spraying;
2. The right panel and operation buttons of the equipment are easy to use and beautiful in appearance.
3. The equipment is equipped with a protective box, and the test is carried out in the box for safety protection;
4. The equipment can be connected to external loads to realize the electrical life test of the product, 3-station independent current.
Load cabinet: AC380V±10% 50Hz, 15kVA,
Life testing machine: AC380V±10% 50Hz, 3kVA
Working temperature 0-40℃ Humidity 30%-90%;
PLC intelligent integrated control, man-machine touch interface operation
Mode 1: Circuit breakers with rated current not exceeding 32A:
The operating frequency is 240 operating cycles per hour (4 times/min). The circuit breaker shall remain open for at least 13 seconds during each operating cycle.
Mode 2: Circuit breaker with rated current greater than 32A:
The operating frequency shall be 120 operating cycles per hour (2 times/min). The circuit breaker shall remain open for at least 28 seconds during each operating cycle.
Mode three, custom
Mode 1 and mode 2 can directly call the program, and mode 3 is for the customer to set parameters by himself
MCB mounted on dark black plywood painted 20mm thick
The height range can be adjusted up and down to match the different strokes of the sample switch
Application
It is used to conduct mechanical and electrical life tests on miniature molded case circuit breakers to assess whether the circuit breaker will experience excessive wear after 4,000 operating cycles, the position of the moving contact is inconsistent with the corresponding position of the indicating device, and the casing is damaged enough to be tested. Access to live parts, loose electrical and mechanical connections, leakage of sealing compounds, etc. to determine compliance with the standard
Test principle
This testing machine adopts PLC touch screen independent control system to complete the automatic control of the test product. The action mechanism cooperates with the load on-off to realize the durability operation test of the test product. It can complete the statistical summary of the number of tests, and the closing time and opening time can be set.
