IEC 60898-1 Circuit Breaker Tripping Characteristics Temperature Rise Test Machine

IEC 60898-1 Circuit Breaker Tripping Characteristics Temperature Rise Test Machine

Product overview:

The test equipment is designed and manufactured according to the standard requirements of

IEC60898-1 clause 9.8, 9.9 and 9.10, IEC 60947-1 clause 7.2.1 and etc.

It is made to verify that the circuit-breaker complies with the requirements, which apply 1.13 times, 1.45 times, and 2.55 times the rated current to test to see if it trips within the specified time. The test equipment can also test the instantaneous tripping characteristics of the circuit breaker, that is, apply 3 to 20 times the rated current for the test whether it jumps out of the time. Also meets standard 28-day test and temperature-rise test requirements.

It is suitable for online testing of molded case circuit breakers and miniature circuit breakers before leaving the factory. It is a necessary equipment for electrical performance testing of circuit breaker manufacturers.

Technical parameters:

Equipment characteristics:

The equipment chamber is welded with high-quality steel, the plate is coated and sealed, and the surface is anti-static, anti-rust, and anti-corrosion coated. The upper part of the equipment is equipped with a panel, a power switch, and a variety of wire ends (for delay tripping test). The equipment is reasonably designed and used with the advantages of convenience, simple operation, reliable performance and beautiful appearance.

According to the delayed tripping of standard IEC60898-1 clause 9.10.2.1 or 9.10.2.2, the chambers in SN2501C can be tested independently at the same time. According to the instantaneous test of IEC60898-1 clause 9.10.3.2-9.10.3.4, it can only be tested in different time.

Chamber is equipped with a heating device, with a temperature control range of RT+5~50°C, so that the model samples in the chamber can be used at normal ambient temperatures, and includes a three-way ambient temperature monitoring function.

The software must allow the execution of any test program to be terminated at any time without having to wait for the standard procedure to complete, retaining the results obtained at the time of termination.

Test principle:

This test equipment adopts the principle of low voltage and high current output, uses the large current in the machine to isolate the output current of the transformer, sets the current size through the touch screen, and the constant current source adjusts the size of the output current of the transformer, which has the function of automatically stabilizing the current. It has an option of setting the test time using the touch screen and comparing the test trip time to evaluate the quality of the circuit breaker.
