Technical Field

[0001] The utility model relates to the technical field of electrical testing, in particular to a multi-station RCD module protection characteristic testing system. Background Art

[0002] Leakage protection is a very important and indispensable protection in people's daily production and life, especially in humid and easily contaminated environments such as shower rooms and kitchens. Leakage protection is a must to ensure personal safety. Therefore, various types of leakage protection products came into being. Billions of leakage protection products are produced every year and applied to people's daily lives. High-quality leakage protection products are a matter of life and death, and full-function performance testing can guarantee the quality of their products. However, there is a lack of multi-station testing systems on the market that can increase production capacity and reduce equipment and labor costs.

[0003] In order to increase production capacity, purchasing multiple RCD testers and configuring multiple workers requires huge investment in funds and labor costs. There are problems of low testing efficiency and high cost, which cannot meet the needs of large-scale production and has low economic benefits. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a multi-station RCD module protection characteristic testing system.

[0005] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a multi-station RCD module protection characteristic test system, comprising: an RCD tester, used to independently realize the complete test of the protection characteristic of the RCD module; a multi-station module tooling, used to carry multiple RCD modules; a multi-station module controller, used to cooperate with the RCD tester to realize the test of the protection characteristic of the multi-station RCD module (4);

[0006] The RCD tester and the RCD module are connected with a leakage current circuit, which is used to provide the leakage current required for the RCD module test. The leakage current flows out from the L1 port of the RCD tester, flows through each RCD module in series, and then returns to the L1' port; the RCD tester and the multi-station module controller are connected with a communication circuit; the RCD tester provides a test synchronization signal to the multi-station module controller through the active port; a power supply circuit is connected between the multi-station module tooling and the RCD module.

[0007] As a preferred solution of the utility model, the multi-station module tooling includes a signal receiving device, and the signal receiving device is used to receive the tripping action signal of each RCD module.

[0008] As a preferred solution of the utility model, the multi-station module tooling includes a signal sending device, which is used to send the received RCD module tripping action signal to the multi-station module controller, and send the test mode signal, calibration mode signal and reset mode signal to the RCD tester.

[0009] As a preferred solution of the utility model, the power supply circuit provides independent power supplies VCC and GND to each RCD module.

[0010] As a preferred solution of the present invention, the test system further comprises a display device for displaying the test results and status information during the test process.

[0011] As a preferred solution of the present utility model, the multi-station module tooling is provided with twenty stations.

[0012] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0013] The utility model realizes the simultaneous and parallel testing of multiple RCD modules by adopting an RCD tester in conjunction with a multi-station module controller and a multi-station module tooling, thereby improving the test efficiency and reducing the test system cost and labor cost without increasing the number of test hosts. Under the demand of achieving the same production capacity, the test system cost is reduced by about 80%, the labor cost is reduced by 90%, and huge economic benefits are achieved. At the same time, since independent power supplies VCC and GND are used to power each RCD module, the accuracy and reliability of the test are guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Example 1

[0019] like Figure 1 , Figure 2 As shown, a specific embodiment of a multi-station RCD module protection characteristic test system described in the utility model includes an RCD tester 1, a multi-station module controller 3 and a set of multi-station module tooling 2. The RCD tester 1 provides the leakage current required for the test to the RCD module 4 on the multi-station module tooling 2 through the leakage current circuit 5. The multi-station module tooling 2 carries multiple RCD modules 4 and provides independent power supplies VCC and GND for each RCD module 4. The multi-station module controller 3 communicates and transmits data with the RCD tester 1 through the communication circuit 6.

[0020] During the test process, the RCD tester 1 sends a test synchronization signal 12 to the multi-station module controller 3 through the communication circuit 6 to start the test process. The signal receiving device on the multi-station module tooling 2 receives the tripping action signal 11 of each RCD module 4, and sends the tripping action signal 11 to the multi-station module controller 3 through the signal sending device. At the same time, the multi-station module tooling 2 also sends a test mode signal 7, a calibration mode signal 8 and a reset mode signal 9 to the RCD tester 1 through the signal sending device.

[0021] After the test is completed, the RCD tester 1 displays the test results and status information during the test through the display device.

[0022] In this embodiment, the multi-station module tooling 2 is provided with twenty stations. By matching a 20-station module controller and a 20-station module tooling, 20-station RCD modules can be tested simultaneously and in parallel.

[0023] The multi-station RCD module protection characteristic test system in this embodiment can test multiple RCD modules 4 in parallel at the same time, thereby improving the test efficiency and reducing the test system cost and labor cost. At the same time, since independent power supplies VCC and GND are used to power each RCD module 4, the accuracy and reliability of the test are guaranteed.

Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods, so they will not be described in detail here.

Various changes can be made within the knowledge of ordinary technicians in the field without departing from the purpose of the present invention, and modifications or deformations without creative labor are still within the scope of protection of the present invention.
