Multifunctional integrative life experimental platform and its control method

Abstract

The present invention relates to a multifunctional comprehensive service life test-bed and the control method thereof. The present invention includes a test device with a plurality of types of automatic opening and closing breakers and a breaker undervoltage action detecting device, and also includes a control device, and a power supply device. The control device includes an industrial control computer, a touch screen, a control circuit of a stepping motor and a voltage regulating motor, and a control signal input / output circuit. The power supply device includes a 1-20 routes of test used power supply, wherein, a manual adjustable supply, an automatic adjustable power supply, a direct current manual adjustable power supply, and a fixed power supply are included. The present invention adopts the two technologies of the test device with a plurality of types of automatic opening and closing breakers and a breaker undervoltage action detecting device, and can test the service lives of different types of plastic shells and frame type breakers, the alternating / direct current contactor and the accessory products thereof on the same test-bed. The present invention improves the detecting precision of the delay undervoltage property, and uses the rational match of the types of the power supply to realize more temporary tests besides the prescribed test.

Description

Technical field [0001] The invention belongs to a product life test device for circuit breakers and contactors, in particular to a multi-functional comprehensive life test bench capable of performing life tests of various types of circuit breakers and contactors at the same time and a control method thereof. Background technique [0002] Currently known life tests on different types of molded case circuit breakers, frame circuit breakers, AC / DC contactors, and accessories thereof are mostly done manually. First of all, during the inspection process, the life tests of molded case circuit breakers, frame circuit breakers and contactors generally need to be completed on different test benches, which not only is not conducive to saving costs, but also reduces work efficiency; secondly, due to the update of product models The speed of replacement is accelerating, and the function of a single type of life test bench is far from meeting the needs. It is necessary to rebuild a tempo...

Problems solved by technology

First of all, during the inspection process, the life tests of molded case circuit breakers, frame circuit breakers and contactors generally need to be completed on different test benches, which not only is not conducive to saving costs, but also reduces work efficiency; secondly, due to the update of product models The speed of replacement is accelerating, and the function of a single type of life test bench is far from meeting the needs. It is necessary to rebuild a temporary circuit during the test, which will make it difficult to measure the test process with a unified standard and the circuit is prone to accidents. At the same time, the test equipment It is also not attractive in appearance; at last the known detection equipment generally all has too simple structure, low degree of automation, high labor intensity, low detection accuracy, inability to adjust the detection method, inadequacies such as test data cannot be preserved, and some important characteristics (such as delay There is no high-precision detection method in the test of the return time of the undervoltage characteristic
