Description

Technical Field

[0001] The utility model relates to the field of auxiliary switch detection, in particular to an auxiliary switch detection platform. Background Art

[0002] The auxiliary switch is part of the main switch and is configured in power equipment such as high-voltage or medium-voltage circuit breakers and disconnectors to serve as the opening, closing, signal control and interlocking protection of the secondary control circuit. It can also be used as a combination switch and transfer switch. The name of the auxiliary switch contains the word "auxiliary" because it is not an independent switch. It is a carrier for auxiliary disconnection, connection and interlocking functions in the control system. After the auxiliary switch is produced, it is necessary to conduct finished product testing to ensure that the auxiliary switch produced is fault-free. The traditional auxiliary switch test bench has a complex structure and complex operation.

[0003] Therefore, it is necessary to design an auxiliary switch testing station with simple structure and easy operation. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the traditional auxiliary switch detection platform has a complex structure and complex operation.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide an auxiliary switch detection platform, the detection platform includes a platform body, a limit frame is installed on the upper surface of the platform body, a plurality of contact columns are arranged inside the limit frame, an air push cylinder B is fixedly installed on the upper surface of the platform body, the air push cylinder B is located on the right side of the limit frame, a push rod B is installed on the side of the air push cylinder B close to the limit frame, and the other end of the push rod B is fixedly connected to a conductive push sheet.

[0006] The side wall of the platform is fixedly connected with a support rod, the other end of the support rod is fixedly connected with an air push cylinder, a push rod A is installed at the bottom of the air push cylinder A, and the other end of the push rod A is fixedly connected with a pressing sheet.

[0007] A plurality of on-off indicator lights are installed on the front side of the platform, and the plurality of on-off indicator lights correspond to and are connected with a plurality of contact posts one by one.

[0008] The beneficial effects of the utility model are as follows:

[0009] By providing a conductive push piece, a pressure piece and an on-off indicator light, several contact posts are energized, and the auxiliary switch to be tested is placed in the limit frame so that the auxiliary switch contacts the contact post. Then, the air push cylinder B is controlled so that the push rod B pushes the conductive push piece to push the push rod switch of the auxiliary switch into the interior thereof, thereby forming a pathway between the contact and the contact post for testing the contact. After the auxiliary switch is placed in the limit frame, the air push cylinder A is started so that the push rod A drives the pressure piece to move downward to fix the auxiliary switch to prevent the auxiliary switch from being lifted during the testing process, resulting in inaccurate testing. Several groups of on-off indicator lights are connected in series with several contact posts to form a pathway. When the push rod switch of the auxiliary switch is pushed in, if the contact is normal, the corresponding on-off indicator light is on, and if there is a problem with the contact, the corresponding on-off indicator light is off, so that it can be known which specific contact has a problem.
