标题(英语)

Insulating resistance tester of 30 loop thin-membrane capacitor


摘要(英语)

The utility model relates to an insulating resistance tester for thirty thin-membrane capacitors, which is composed of an outer shell, a panel, a main control board and an inserting board correspondingly provided with a test clamp which are connected; the circuit of the main control board is provided with a DC test power supply part and a test circuit part, wherein the DC test power supply part comprises a high-voltage AC commutation filtering circuit, a switch circuit, a partial pressure output circuit, a regulation circuit and a test voltage output circuit; the test part comprises a test voltage circuit, a signal amplification circuit, a comparator circuit, a result output circuit, a multiplying factor control circuit, a digital-to-analogue converter circuit and a reference voltage circuit. The tester adopts a common test power supply of a rapid charging on a voltage aspect, and one loop test voltage can be simultaneously used by thirty loops. On the aspect of multiplying power control, the test multiplying power of each loop adopts a miniature relay to control and to convert; a relay is completely isolated from a test circuit in electricity, which is favorable to improve test accuracy of the tester. The tester can simultaneously and fast test thirty capacitors, with high efficiency, energy saving and low cost.
