Online automatic insulation voltage resistance testing system

Abstract

The invention provides an online automatic insulation voltage resistance testing system which comprises the components of: a PLC controller, a high-voltage accessing device, a conductive seat, a GND accessing device and an insulating voltage resisting instrument. A first cylinder and a second cylinder are respectively arranged in the high-voltage accessing device and the GND accessing device. The first cylinder and the second cylinder are respectively controlled by the PLC controller and synchronously acts. The insulating voltage resisting instrument is electrically connected with the high-voltage accessing device, the GND accessing device and the PLC controller respectively. In test, the GND accessing device is electrically connected with the conductive seat. According to the online automatic insulation voltage resistance testing system, the PLC controller causes the first cylinder to control conduction or disconnection between the high-voltage accessing device and a product to be tested, and simultaneously causes the second cylinder to control conduction or disconnection between the GND accessing device and the product to be tested through the conductive seat; and the PLC controller transmits a signal according to testing result of the insulating voltage resisting instrument, thereby realizing automatic online detection in insulating voltage resisting test, saving test manpower, improving manual operation efficiency, and preventing misjudgement caused by manual fault.

Description

technical field [0001] The invention relates to the technical field of automatic insulation and withstand voltage testing, in particular to an online automatic insulation and withstand voltage testing system. Background technique [0002] In the production of electrical appliances, such as the production of televisions, on-line insulation and withstand voltage testing of televisions is the most important testing process in the production of televisions. Electrical products such as televisions must pass the insulation withstand voltage test before they can be offline, so as to ensure the electrical safety performance of electrical products such as televisions. [0003] The existing on-line insulation and withstand voltage testing of TVs and other products is mainly carried out through manual testing. The debugging lines of TVs and other products use differential speed chain lines to transport the TVs waiting to be tested on the tooling board. When the online After the produc...

Problems solved by technology

Since this simple manual testing method is a simple and repetitive operation, it is not conducive to the testers to concentrate on making judgments on the test results, and it is easy to cause false unqualified products or false qualified products caused by manual errors, reducing production efficiency and product quality.
