Description

Technical Field

[0001] This utility model belongs to the technical fields of speed-regulating motors, electronic circuits, etc., and in particular relates to a high-voltage withstand voltage test device. Background Technology

[0002] High-voltage testing systems, due to their high voltage levels (95kV, 35kV, 13.7kV, 1kV), require operators to manually control the equipment at close range via autotransformers, posing significant safety hazards and being unsuitable for current state-of-the-art technologies. To address the electrical design and application demands arising from this technological advancement, a device was developed to meet the equipment control requirements. Summary of the Invention

[0003] This utility model aims to solve the problem that there are great safety hazards in the operation of high-voltage test equipment with high voltage levels (95kV, 35KV, 13.7KV, 1KV) when operators manually control the test equipment on site through multiple autotransformers. Therefore, it provides a high-voltage withstand voltage test device that can remotely control the high-voltage test system, realize remote start, stop, test voltage adjustment, timing and other actions, and ensure the safety of operators.

[0004] To achieve the above-mentioned utility model objectives, this utility model provides a high-voltage withstand voltage test device, including a power module, a reversible geared motor, an intermediate relay, a multi-circuit wireless remote control receiver, a five-channel remote control, and an autotransformer. The multi-loop wireless remote control receiver is compatible with a five-channel remote control. The multi-loop wireless remote control receiver includes five channels, namely: The first node connection is connected to the start button of the high-voltage tester to enable remote control start of the high-voltage tester; The second node connection is connected to the stop button of the high-voltage tester to enable remote control of the high-voltage tester to stop. The third node is connected to the coil of the intermediate relay KA1 to load it with 12V DC, thereby closing the two nodes of the intermediate relay KA1 and loading it through its circuit to the commutator geared motor to achieve clockwise operation. The motor spindle is connected to the spindle of the autotransformer (6) in the control box of the high voltage tester. The rotation of the motor drives the autotransformer to rotate, thereby increasing the test voltage of the high voltage transformer. The fourth node is connected to the coil of intermediate relay KA2 to load it with 12V DC, thereby closing both nodes of intermediate relay KA2 and reversing the load through its circuit to the commutator geared motor, enabling it to run counterclockwise. The motor's main shaft is connected to the main shaft of the autotransformer in the high-voltage tester's control box. The motor's rotation drives the autotransformer, reducing the test voltage of the high-voltage transformer. The fifth node connection is connected to the timing button of the high voltage tester, thereby realizing remote control timing of the high voltage tester; The AC 220V is introduced into the power module through a three-prong plug, and two DC 12V outputs are generated through its internal circuitry. One output is connected to a multi-channel wireless remote control receiver, and the other output is connected to intermediate relays KA1 and KA2.

[0005] This invention enables remote control of the high-voltage tester by pressing buttons 1 to 5 on a five-channel remote control. Each node within the multi-channel wireless remote control receiver is activated, and the receiver is connected to the internal wiring of the high-voltage tester via wires. This allows for remote control of the tester's start, stop, voltage increase, voltage decrease, and timing functions. This ensures that during high-voltage testing, operators can stay away from ultra-high-voltage live parts and can remotely operate the equipment even in special environments.

[0007] To better understand the purpose, structure, and function of this utility model, a high-pressure withstand test device of this utility model will be described in further detail below with reference to the accompanying drawings.

[0008] Reference Figure 1 and Figure 2 The high-voltage withstand test device of this utility model includes a power supply module 1, a reversible geared motor 2, an intermediate relay 3, a multi-circuit wireless remote control receiver 4, a five-channel remote control 5, an autotransformer 6, and wiring terminals 7. The multi-loop wireless remote control receiver 4 is matched with the five-channel remote control 5.

[0009] The multi-loop wireless remote control receiver 4 includes five channels, namely: The first node connection is connected to the start button of the high-voltage tester to enable remote control start of the high-voltage tester.

[0010] The second node connection is connected to the stop button of the high-voltage tester to enable remote control of the high-voltage tester to stop.

[0011] The third node is connected to the coil of intermediate relay KA1 to load it with 12V DC, thereby closing the two nodes of the intermediate relay and loading the commutative geared motor through its circuit, enabling it to run clockwise. The motor spindle is connected to the spindle of autotransformer 6 in the high-voltage tester control box. The rotation of the motor drives the autotransformer to rotate, increasing the test voltage of the high-voltage transformer.

[0012] The fourth node is connected to the coil of intermediate relay KA2 to load it with 12V DC, thereby closing the two nodes of the intermediate relay and reversing the load through its circuit to the commutator geared motor, enabling it to run counterclockwise. The motor's main shaft is connected to the main shaft of autotransformer 6 in the high-voltage tester control box. The motor's rotation drives the autotransformer, reducing the test voltage of the high-voltage transformer.

[0013] The fifth node is connected to the timing button on the high-voltage tester, thereby enabling remote control timing of the high-voltage tester.

[0014] The power module 1, multi-circuit wireless remote control receiver 4, five-channel remote control 5, intermediate relay 3, and geared motor 2 are connected to each other via terminal blocks.

[0015] The AC 220V is introduced into the power module through a three-prong plug, and two DC 12V outputs are generated through its internal circuitry.

[0016] Press the No. 1 start button on the handheld wireless remote control, and the multi-channel wireless remote control receiver will receive a signal. The first node will close, and its node connection will be connected to the start button of the high voltage tester, thereby realizing the remote control start of the high voltage tester.

[0017] Pressing button #3 on the handheld wireless remote control activates the multi-channel wireless receiver, closing the third node. This node connects to the coil of intermediate relay KA1, applying 12V DC current. This, in turn, closes the other two nodes of the intermediate relay, which in turn supply power to the commutator geared motor, causing it to rotate clockwise. The motor's main shaft is connected to the autotransformer's main shaft in the high-voltage tester's control box. The motor's rotation drives the autotransformer, increasing the test voltage of the high-voltage transformer.

[0018] Pressing the No. 5 timing button on the handheld wireless remote control activates the multi-channel wireless remote control receiver, closing the fifth node. The node's connection is then connected to the timing button on the high-voltage tester, thus enabling remote timing control of the high-voltage tester.

[0019] Pressing button #4 on the handheld wireless remote control activates the multi-channel wireless remote receiver, closing the fourth node. This node connects to the coil of intermediate relay KA2, applying 12V DC current. This, in turn, closes the other two nodes of the intermediate relay, and the current is reversed through its circuit to the commutator geared motor, causing it to run counter-clockwise. The motor's main shaft is connected to the main shaft of the autotransformer in the high-voltage tester's control box. The motor's rotation drives the autotransformer, thus reducing the test voltage of the high-voltage transformer.

[0020] Pressing the No. 2 stop button on the handheld wireless remote control will trigger a signal from the multi-channel wireless remote control receiver, closing the second node. The node's connection is then connected to the stop button on the high-voltage tester, thus enabling remote control stopping of the high-voltage tester.

[0021] The basic principle of the high-voltage withstand voltage test remote control device is as follows: By pressing buttons 1 to 5 on the five-channel remote control, the operation of each node within the multi-channel wireless remote control receiver is achieved. These nodes are then connected to the internal wiring of the high-voltage tester via wires, enabling remote control of the high-voltage tester's start, stop, voltage increase, voltage decrease, and timing functions. This ensures that during high-voltage testing, operators can stay away from ultra-high-voltage live parts and, in special environments, leave the operating equipment to perform remote control operations.
