Switch capacitor contactor resistance wire detection fixture

Abstract

The invention relates to a switch capacitor contactor resistance wire detection fixture. The fixture comprises a transmission mechanism and a detection system; the transmission mechanism comprises a driving device, a support plate and a guide rail, the detection system comprises a machine box and a detection contact, a to-be-detected contactor is arranged on the support plate which is arranged ona guide rail and connected with a driving device through a transmission rod, the support plate is driven by the driving device and slips on the guide rail, the support plate is provided with a test position, and when the support plate moves to the test position, the detection contact make contact with the to-be-detected contactor. Accordingly, by means of an electricity and mechanism combination mode, the automatic detection function is achieved, and the fixture is applicable to requirements of lean production and product promotion of an existing company.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a jig for testing resistance wire continuity of a switching capacitor contactor. Background technique [0002] Switched capacitor contactors are mainly used for AC 50Hz / 60Hz, rated working voltage up to 690V, in the power system under the AC-6b use category, to connect and break parallel capacitors. It consists of a contactor, a current-limiting contact group and six current-limiting resistance wires (referred to as resistance wires), and the current-limiting contact group and six resistance wires constitute a surge current suppression device. After the switching capacitor contactor is assembled, it is necessary to check the on-off situation of the six resistance wires and the cross-connection between different main circuits, so as to prevent the problem of the resistance wire from affecting the key functions of the product. [0003] In the industry, the on-off d...

Problems solved by technology

[0003] In the industry, the on-off detection of resistance wires is generally observed and measured by naked eyes and simple equipment such as a multimeter to judge whether the wiring position of the resistance wires is correct and whether the resistance wires are broken. The work efficiency and accuracy are very low, which is affected by human factors (fatigue, mistakes) The impact of the problem is very great, and the risk of the defective product leaving the factory is very high. When the customer uses it, the key function of the product will fail, resulting in a very poor experience for the user, resulting in customer complaints and a decline in trust in the company.
