Connection detection device of dielectric strength tester and connection detection method thereof

Abstract

The invention discloses a connection detection device of a dielectric strength tester and a connection detection method thereof. The connection detection device of the dielectric strength tester comprises an impedance detection module, a programmable logic gate, a microprocessor and a high-voltage output module. The impedance detection module is used for detecting electrical connection between the connection detection device of the tester and a product to be detected and generating pushing signals. The microprocessor is used for receiving signals of the programmable logic gate and controlling the high-voltage output module according to connection conditions between the connection detection device of the tester and the product to be detected. The connection detection method can monitor whether the contact between the product to be detected and the connection detection device of the tester is reliable during the whole test, and test quality of the product to be detected is ensured. The connection detection method is performed by fully ensuring that the product to be detected is in a good connection state, and accuracy of the final test results can be ensured.

Description

technical field [0001] The invention relates to the technical field of withstand voltage testing, in particular to a connection detection device of a withstand voltage tester and a connection detection method thereof. Background technique [0002] In order to ensure the practical safety of products, especially electrical products, safety tests, such as leakage current tests and withstand voltage tests, will be carried out before they are manufactured and offline. In recent years, due to the increase in the amount of testing required by relevant laws and regulations year by year, the testing procedures have become more stringent, in anticipation of the products under test that can indeed detect defective or borderline defective products. At present, most electrical appliance manufacturers use traditional test methods or traditional test circuit structures. However, this traditional test method or test circuit structure is difficult to detect whether the contact between the te...
