Embodiment 1

[0030] Please refer to figure 2 with image 3 , figure 2 It is a schematic diagram of a small circuit breaker detection system provided by the first specific embodiment of the present invention; image 3 for figure 2 Schematic diagram of the connection of the current generation unit of the miniature circuit breaker detection system shown.

[0031] The miniature circuit breaker detection system provided by the first embodiment of the present invention includes a main control board 201 and a current generation unit 202 . The current generating unit 202 includes a primary voltage regulating device 301 and a secondary voltage regulating device 302 . Among them, the primary voltage regulating device 301 is arranged between the power supply 303 and the tested miniature circuit breaker 304, and is used to regulate the voltage at both ends of the tested miniature circuit breaker 304 according to the control parameters of the main control board 201 to meet the test requirements;...

Embodiment 2

[0036] In the miniature circuit breaker detection test, it is required to test whether the temperature rise of the terminal of the miniature circuit breaker exceeds the allowable value. In general, the allowable value of temperature rise is 15K. In the actual operation of the existing technology, the temperature rise of the terminal of the tested miniature circuit breaker is measured in the last cycle of the test, and the temperature rise of the terminal of the tested miniature circuit breaker has already exceeded the allowable value in the first few cycles of the test. And the inspectors don't know, continue to carry out the situation of follow-up test, so will waste time and energy in vain. In order to monitor whether the temperature rise of the terminal of the tested miniature circuit breaker exceeds the allowable value during the long detection test of the miniature circuit breaker, the present invention provides a second specific implementation manner.

Embodiment 3

[0046] Figure 5 It is a schematic diagram of a small circuit breaker detection system according to the third embodiment of the present invention. On the basis of the first specific implementation manner, as a preferred implementation manner, the third specific implementation manner of the present invention further includes a data feedback unit 501 .

[0047] The data feedback unit 501 is arranged in the circuit where the tested miniature circuit breaker 304 is located, and is used to collect the actual measurement signal of the circuit where the tested miniature circuit breaker 304 is located to feed back to the main control board 201 .

[0048] It should be noted that the actual measurement signal collected by the data acquisition unit 501 is specifically the actual current flowing through the tested miniature circuit breaker 304 , and may also include the actual voltage across the tested miniature circuit breaker 304 after passing through the primary voltage regulating devi...

Abstract

The invention discloses a miniature circuit breaker detection system comprising a current generation unit and a main control panel used for controlling the current generation unit. The current generation unit comprises a primary voltage regulating device and a secondary voltage regulating device. The primary voltage regulating device is arranged between a power supply and a detected miniature circuit breaker and used for regulating and controlling the voltage of the two ends of the miniature circuit breaker according to the control parameters of the main control panel so as to meet the test requirements. The secondary voltage regulating device is arranged between the detected miniature circuit breaker and a load and used for regulating the voltage of the two ends of the load according to the control parameters of the main control panel. The voltage of the two ends of the load is increased by the secondary voltage regulating device so that the current flowing through the load can be reduced. Meanwhile, the load can be the reactive load and the active loss of the load can be further reduced so that the active loss of the whole system can be reduced and the stability of the whole system can be enhanced.

Description

technical field [0001] The invention relates to the field of electrical product detection, in particular to a small circuit breaker detection system. Background technique [0002] Miniature Circuit Breaker (Miniature Circuit Breaker), also known as Micro Circuit Breaker (Micro Circuit Breaker), is mainly used for AC 50HZ or 60HZ, rated voltage below 400V, rated operating current below 63A, and has the ability to protect the overcurrent of building line facilities. Functions and similar uses are important protective devices for safe electricity use in civil buildings. The quality of its products is directly related to the safety of life and property of the masses. Quality inspection before miniature circuit breakers are put into use is very important. Among them, the 28-cycle test for miniature circuit breakers is not a necessary inspection item for delivery, but it is a necessary item for certification. See figure 1 , figure 1 It is a schematic diagram of the connection o...
