Description

Technical Field

[0001] This application belongs to the technical field of electrical component detection. Specifically, it relates to a rapid grounding test device with variable hole pitch. Background Art

[0002] A terminal block is an electrical component used to connect electrical equipment and cables. It usually consists of one or more rows of terminals, and each terminal has one or more wiring holes for connecting wires or cables. Terminal blocks are widely used in fields such as electrical control cabinets, distribution boxes, and automation equipment, and are important components for realizing electrical connection and signal transmission. The main purpose of the short-circuit test of the terminal block is to ensure good electrical connection performance of the terminal block, check the insulation performance between each terminal on the terminal block, and verify the reliability and safety of the terminal block under actual working conditions. Through the short-circuit test, potential electrical faults or safety hazards can be detected in a timely manner, thus ensuring the normal operation of the power system.

[0003] In power production, it is often necessary to conduct insulation tests on the temperature of generator stator coils, iron cores, and stator bars. This type of work requires first removing the wiring from the on-site temperature measuring elements to the DCS card terminals, and then serially short-circuiting and grounding the protection of each card terminal one by one. The number is at least dozens, and at most hundreds or thousands, and the workload is huge. When the construction period is tight, both the removal and reinstallation require a lot of energy and are prone to errors. Long-term disassembly and installation also cause a certain degree of wear to the terminal block, posing a safety hazard to the safe and stable operation of the equipment. Some manufacturers may have matching short-circuit terminal block pins, but different working conditions require different terminal blocks (different models of the same manufacturer, or different models of different manufacturers). Since the terminal models are different and the hole pitch is not fixed, when conducting the above tests, the number of spare parts required will be huge, greatly increasing the maintenance cost, and at the same time greatly increasing the time to complete the above tests. There is an urgent need to thoroughly solve the above problems in terms of material cost and time cost. Summary of the Utility Model

[0018] In order to make the purpose, technical solutions and advantages of this application clearer, the following further details this application in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0019] Before describing the various embodiments of the present application in detail, the technical concept of the present application will be briefly described first: Currently, when testing a terminal block, it is usually necessary to remove the block, which is likely to damage the block and consume a great deal of effort. If a matching short-circuit terminal block pin is used, it is difficult to meet the requirements of measuring terminal holes with different pitch distances under different working conditions. For this reason, the present application provides a quick grounding test device with variable pitch distance. A plurality of movable conductive components are installed on a conductive rail. According to different pitch distances, the spacing of each conductive component can be adjusted to insert into the corresponding terminal hole to be measured. On the one hand, the test can be achieved without disassembling the terminal block. On the other hand, it can adapt to terminal holes with different pitch distances, improving the practicality of the test device. The specific principle of the quick grounding test device with variable pitch distance of the present application will be described below with more embodiments.

[0020] Specifically, as Figure 1 shown, the quick grounding test device with variable pitch distance includes a conductive rail 10, an air switch 20, and a plurality of conductive components 30. The air switch 20 is connected to the conductive rail 10. The plurality of conductive components 30 are arranged at intervals and are all movably installed on the conductive rail 10. The conductive components 30 are used to insert into the terminal holes to be measured. The number of the conductive components 30 and the length of the conductive rail 10 can be set according to actual needs.

[0021] In one or more embodiments, the conductive component 30 includes a sliding component and a pin 31. The sliding component is slidably connected to the conductive rail 10. The pin 31 is connected to the sliding component, and the pin 31 is used to insert into the terminal hole to be measured. Exemplarily, the sliding component includes a T-shaped nut 32 and a T-shaped bolt 33. The T-shaped nut 32 is slidably connected to the conductive rail 10. When the T-shaped bolt 33 is connected to and tightened with the T-shaped nut 32, the sliding component is relatively fixed to the conductive rail. Therefore, each T-shaped nut 32 can be slid according to the pitch distance of the terminal hole to be measured. After sliding to a predetermined position, the T-shaped bolt 33 is tightened to keep the pin 31 relatively fixed at the predetermined position. Exemplarily, the pin 31 is fixedly connected to the T-shaped nut 32. For example, the pin 31 can be welded to the outer wall of the nut 32 by welding.

[0022] In one or more embodiments, the air switch 20 is used for grounding, that is, the test grounding is controlled by opening or closing the air switch 20.

[0023] The usage method of the quick grounding test device with variable pitch distance is as follows:

[0024] First, pre - install the T - shaped nut 32 on the conductive rail 10. After adjusting the spacing of the T - shaped nuts 32 according to the hole pitch of the terminal holes to be measured, tighten each T - shaped bolt 33. Then, insert the pin 31 into the terminal holes to be measured that need to be short - circuited. (Here, the order can also be swapped, that is, insert the pin 31 into the terminal holes to be measured that need to be short - circuited and then tighten each T - shaped bolt 33.) According to actual needs, short - circuit the terminals to be short - circuited one by one. Finally, close the air switch 20 to achieve the rapid short - circuit test of the terminal block.

[0025] The rapid grounding test device with variable hole pitch provided by this embodiment has the following effects:

[0026] The rapid grounding test device effectively reduces the frequent disassembly and connection wear of the terminal block, extends the service life of the equipment, and greatly improves the work efficiency. Especially for the protection signals of important equipment, relevant tests can be completed without disconnecting the terminal wiring, directly reducing the risks and potential hazards of human misoperation to zero, effectively ensuring the safe and stable operation of the equipment, and can also adapt to the rapid short - circuit of terminal blocks with different hole pitches.

[0027] The specific implementation manners of the present application have been described in detail above. Although some embodiments have been shown and described, those skilled in the art should understand that these embodiments can be modified and improved without departing from the principles and spirit of the present application defined by the claims and their equivalents, and these modifications and improvements should also be within the protection scope of the present application.
