Description

Technical Field

[0001] The utility model relates to the technical field of power supply spot inspection, in particular to a power supply spot inspection and testing device for a marine socket box. Background Art

[0002] The power socket box is a necessary power supply device in the process of shipbuilding. Therefore, at all stages of shipbuilding, it is particularly important to ensure that the power socket box can operate and be used normally. In order to ensure the safety and reliability of the ship's electrical system, it is necessary to detect whether the power socket box is working properly.

[0003] During the spot inspection operation of the power socket box, it is necessary to first connect the power socket box to an unenergized power cord. After the power cord is connected to the power socket box, power is then supplied to the power cord. However, during the connection process between the power socket box and the power cord, it is not convenient for the operator to determine whether the input end and the output end of the power cord are energized. Therefore, before the wiring operation, the operator needs to use other tools to confirm the energized state of the power cord first, resulting in a cumbersome wiring process between the power socket box and the power cord and low spot inspection efficiency of the power socket box. Summary of the Utility Model

[0004] In order to facilitate power supply to the power socket box and improve the spot inspection efficiency of the power socket box, this application provides a power supply spot inspection and testing device for a marine socket box.

[0005] The power supply spot inspection and testing device for a marine socket box provided by this application adopts the following technical solutions:

[0006] A power supply spot inspection and testing device for a marine socket box includes a box body. An input module and an output module are arranged on the box body. The input module is used for inputting power, and the output module is used for outputting power. A power-on detection module and a power supply detection module are arranged on the input module. The power-on detection module is used for detecting the energized state of the input module, and the power supply detection module is used for detecting the energized state of the output module. A control module is arranged between the input module and the output module, and the control module is used for controlling the on-off of the input module and the output module.

[0007] By adopting the above technical solutions, when power is supplied to the input module, the power-on detection module shows that the input module is energized. When spot inspecting the power socket box, the socket box is connected to the output module. Then, the control module connects the input module and the output module. The input module supplies power to the output module, and the output module supplies power to the power socket box. Moreover, the power supply detection module shows that the output module is energized, so that it is convenient for the operator to directly judge the energized states of the power input end and the power output end. Before the operator connects the socket box to the output module, there is no need to use other tools to detect the energized state of the power cord, simplifying the wiring process of the power socket box, achieving the effect of facilitating power supply to the power socket box, and improving the spot inspection efficiency of the power socket box.

[0008] Preferably, the input module includes a DC interface and a DC circuit breaker. The DC interface is connected to the input end of the DC circuit breaker.

One end of the DC power supply lamp is connected to the positive pole of the output end of the DC circuit breaker, and the other end of the DC power supply lamp is connected to the negative pole of the output end of the DC circuit breaker.

[0009] By adopting the above technical solution, when an operator determines whether the DC interface is energized, the DC circuit breaker is closed. If the DC power supply lamp emits light, it proves that 36V DC power is connected to the DC interface, achieving the effect of quickly detecting the energized state of the DC input end.

When the high-voltage circuit breaker is closed, the high-voltage power transmission lamp emits light. When an operator judges whether the high-voltage interface is energized, the high-voltage circuit breaker is closed.

If the DC power supply lamp 41 is on and the DC supply lamp 51 is off, it proves that 36V DC power is connected to the DC interface 21, but the DC alligator clip 31 is not charged. Then connect the DC alligator clip 31 to the DC power plug box. After the DC alligator clip 31 is connected to the DC power plug box, press the DC normally open switch 611. The first auxiliary contact, the second auxiliary contact, and the main contact of the DC relay 61 are closed, and the DC supply lamp 51 is on, proving that 36V power is connected to the DC socket box. After the inspection of the DC socket box is completed, press the DC normally closed switch 612. The first auxiliary contact, the second auxiliary contact, and the main contact of the DC relay 61 are disconnected, thereby stopping the supply of 36V power to the DC socket box.

[0046] When inspecting the three-phase power plug box, first close the DC circuit breaker 211, and then close the high-voltage circuit breaker 221. If the DC power supply lamp 41 and the high-voltage power supply lamp 42 are on, and the high-voltage supply lamp 52 is off, it proves that 380V three-phase power is connected to the high-voltage interface 22, but the high-voltage alligator clip 32 is not charged. Then connect the high-voltage alligator clip 32 to the three-phase power plug box. After the high-voltage alligator clip 32 is connected to the three-phase power plug box, press the high-voltage normally open switch 621. The first auxiliary contact, the second auxiliary contact, and the main contact of the high-voltage relay 62 are closed, and the high-voltage supply lamp 52 is on, proving that 380V power is connected to the three-phase socket box. After the inspection of the three-phase socket box is completed, press the high-voltage normally closed switch 622. The first auxiliary contact, the second auxiliary contact, and the main contact of the high-voltage relay 62 are disconnected, thereby stopping the supply of 380V power to the three-phase socket box.

[0047] When checking a single-phase power plug-in box, first close the DC circuit breaker 211, and then close the low-voltage circuit breaker 231. If the DC power supply lamp 41 and the low-voltage power supply lamp 43 are on, and the low-voltage supply lamp 53 is off, it proves that 220V single-phase power is connected to the low-voltage interface 23, but the low-voltage alligator clip 33 is not energized. Then connect the low-voltage alligator clip 33 to the single-phase power plug-in box. After the low-voltage alligator clip 33 is connected to the single-phase power plug-in box, press the low-voltage normally open switch 631, and the first auxiliary contact, the second auxiliary contact, and the main contact of the low-voltage relay 63 are closed, and the low-voltage supply lamp 53 is on, proving that 220V power is connected to the single-phase power socket box. When the inspection of the single-phase power socket box is completed, press the low-voltage normally closed switch 632, and the first auxiliary contact, the second auxiliary contact, and the main contact of the low-voltage relay 63 are disconnected, thereby stopping the supply of 220V power to the single-phase power socket box.

[0048] When the DC power supply lamp 41 is on, the DC interface 21 is connected to 36V DC power; when the DC supply lamp 51 is on, the DC alligator clip 31 outputs 36V DC power. When the high-voltage power supply lamp 42 is on, the high-voltage interface 22 is connected to 380V three-phase power; when the high-voltage supply lamp 52 is on, the high-voltage alligator clip 32 outputs 380V three-phase power. When the low-voltage power supply lamp 43 is on, the low-voltage interface 23 is connected to 220V single-phase power; when the low-voltage supply lamp 53 is on, the low-voltage alligator clip 33 outputs 220V single-phase power. The operator judges the energized state of the power input end and the power output end by observing the on-off state of the indicator lamp. Before the operator connects the socket box to the output module 3, there is no need to use other tools to detect the energized state of the power cord, which simplifies the wiring process of the power socket box, achieves the effect of facilitating the power supply to the power socket box, and improves the inspection efficiency of the power socket box.

[0049] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
