Problems solved by technology
The DC breakdown voltage of a switch-type surge protector refers to the DC voltage value when a slow rise is applied between the poles and the gap finally breaks down. The test process is cumbersome. The traditional test method is to add a discharge tube to On the fixture, then turn the voltage regulator and observe the readings of the ammeter, the test process is slow and inaccurate, the efficiency is low and it is easy to cause injury accidents, it is not suitable for the current cumbersome circuits

Embodiment Construction
[0022] The embodiments of the present invention will be further described in detail below with reference to examples and drawings.
[0023] In this embodiment, the device measures 64 surge protectors at a time, which are arranged in an 8×8 matrix array on the fixture, and the intelligent voltage source is controlled by the acquisition control system (PC host) and the drive module to supply 64 surge protectors. The protector is gradually pressurized and tested at the same time. Each surge protector has a test protection circuit and a corresponding breakdown feedback circuit. The on-off of the two is controlled by the same relay Pi (i=1~64), and the switching is performed through the relay Pi. When the test protection circuit is turned on , the breakdown feedback circuit is in an interrupted state, and after the test protection circuit is interrupted, the breakdown feedback circuit is immediately connected. Therefore, during the test, as the voltage of the intelligent voltage s...

The invention disclosed a multi -channel switch -type surge protector DC breakdown voltage test device, including collecting control systems, driving modules, intelligent voltage sources, test protection circuit modules, and breakdown feedback circuit modules.This device can be measured by several measured protectors at a time, arranged into a matrix array on the fixture, and the intelligent voltage source is controlled by the computer to press the converted protector at the same time.This device designed a test protection circuit for each surge protector. As long as there is a surge protector, the circuit's protection circuit is immediately disconnected.Delivery.The multi -channel switch -type surge protector provided by the present invention DC breakdown voltage test device. After a certain surge protector is cut, immediately disconnects the test protection circuit while starting the breakdown feedback circuit. By collecting and controlling controlThe system learned the breakdown voltage of the surge protector.
Description
technical field [0001] The invention relates to the field of lightning protection, in particular to a DC breakdown voltage testing device for a multi-channel switch-type surge protector. Background technique [0002] Switch-type surge protectors are mainly used for lightning protection in power supply systems and signal systems. Breakdown voltage, the gas inside the surge protector will be ionized immediately and spark discharge will occur. At this time, the surge protector is turned on and is in a short circuit state. ground, so as to protect the follow-up equipment and personal safety. Therefore, breakdown voltage is a very important parameter. The DC breakdown voltage of a switch-type surge protector refers to the DC voltage value when a slow rise is applied between the poles and the gap finally breaks down. The test process is cumbersome. The traditional test method is to add a discharge tube to On the fixture, then turn the voltage regulator and observe the reading o...
