Description

Technical Field

[0001] This utility model relates to the field of power distribution room technology, and more specifically, to a modular safety protection device for power distribution rooms to prevent electric shock. Background Technology

[0002] A power distribution room is an indoor electrical distribution area with low-voltage loads. It mainly distributes electrical energy to low-voltage users and is equipped with medium-voltage incoming lines, distribution transformers, and low-voltage distribution devices. When the power distribution equipment inside the power distribution room is poorly grounded, the equipment casing or metal parts may become electrified. Touching these parts could result in electric shock, and the leakage current cannot be safely conducted to the ground, potentially causing the equipment to overheat or arc, thus increasing the risk of fire.

[0003] Traditional power distribution room equipment is usually grounded, but it is difficult to monitor the grounding status of the equipment in a timely manner. When poor grounding occurs, it is difficult for staff to detect and deal with it in time, which can easily lead to electric shock accidents.

[0004] Therefore, a modular safety protection device for power distribution rooms to prevent electric shock is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a modular safety protection device for power distribution rooms to prevent electric shock, so as to solve the problem of inconvenience in timely monitoring of the grounding status of power distribution equipment.

[0006] To achieve the above objectives, a modular safety protection device for power distribution rooms to prevent electric shock is provided, including an insulating protective cover. A conductive sheet is fixedly installed on the bottom surface of the insulating protective cover. A grounding resistance measuring instrument is electrically connected to one side of the conductive sheet, and a grounding mechanism is electrically connected to one side of the grounding resistance measuring instrument. A circuit breaker is fixedly installed on the outer surface of the insulating protective cover. A height adjustment mechanism is fixedly installed on the back of the insulating protective cover, and a power distribution room wall-mounted plate is sleeved on the surface of the height adjustment mechanism.

[0007] As a further improvement to this technical solution, the grounding mechanism includes a down conductor electrically connected to one side of the grounding resistance measuring instrument, and one end of the down conductor is electrically connected to a grounding body, which is used to introduce charge into the ground.

[0008] As a further improvement to this technical solution, the other side of the grounding resistance measuring instrument is electrically connected to a controller, which is electrically connected to a circuit breaker switch, and the circuit breaker switch is used to protect the circuit.

[0009] As a further improvement to this technical solution, the height adjustment mechanism includes a threaded screw rotatably disposed inside the wall panel of the power distribution room. A height adjustment block is threaded onto the surface of the threaded screw. The height adjustment block is fixedly connected to the back of the insulating protective cover. The height adjustment block is used to adjust the wall-mounted height of the insulating protective cover.

[0010] As a further improvement to this technical solution, a servo motor is fixedly installed on the top surface of the wall panel of the power distribution room. The servo motor is fixedly connected to the top of the threaded screw, and the servo motor is used to drive the threaded screw to rotate.

[0011] As a further improvement to this technical solution, a limiting groove is provided on the surface of the power distribution room wall panel, and the height adjustment block is slidably disposed inside the limiting groove, which facilitates the limiting of the height adjustment block.

[0012] As a further improvement to this technical solution, the edge of the front of the insulating protective cover is hinged to a cover door, and a door lock is fixedly installed on the surface of the cover door for opening and closing the cover door.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In this modular safety protection device for power distribution rooms to prevent electric shock, the power distribution equipment is installed in an insulating protective cover by setting up a grounding resistance measuring instrument, a grounding mechanism, and a circuit breaker. The conductive sheet and the grounding mechanism ground the power distribution equipment. The grounding resistance measuring instrument is used to measure the resistance value. When the resistance value is abnormal, it indicates that the power distribution equipment is not grounded properly. Then, the controller controls the circuit breaker to close the circuit, thereby ensuring that the power distribution equipment is properly grounded and can cut off the power supply in time in case of abnormality, preventing electric shock accidents.

[0015] 2. In this modular safety protection device for the power distribution room, the height adjustment mechanism allows the servo motor to rotate the screw after being powered on, which in turn causes the height adjustment block to rise and fall on the wall panel of the power distribution room. When the power distribution equipment is not in use, the insulating protective cover can be adjusted to a high position in the power distribution room, making it inaccessible to personnel and preventing accidental contact or operation that could result in electric shock.

The conductive sheet 2 and the grounding mechanism 4 ground the power distribution equipment. The grounding resistance measuring instrument 3 measures the resistance value. When the resistance value is abnormal, it indicates that the power distribution equipment is poorly grounded. The controller then controls the circuit breaker 5 to close the circuit, thereby ensuring good grounding of the power distribution equipment and timely disconnecting the power supply in case of abnormalities to prevent electric shock accidents.

[0025] A height adjustment mechanism 6 is fixedly installed on the back of the insulating protective cover 1. With the setting of the height adjustment mechanism 6, the servo motor 8 drives the threaded screw 601 to rotate after being powered on, which in turn drives the height adjustment block 602 to rise and fall on the wall-mounted plate 7 of the power distribution room. When the power distribution equipment does not need to be operated, the insulating protective cover 1 is adjusted to a high position in the power distribution room, which is inaccessible to personnel, thus avoiding accidental contact and operation that could cause electric shock. The wall-mounted plate 7 of the power distribution room is sleeved on the surface of the height adjustment mechanism 6.

[0027] The grounding mechanism 4 serves to ground the power distribution equipment.

[0028] Please see Figure 3 The other side of the grounding resistance measuring instrument 3 is electrically connected to a controller, which is electrically connected to the circuit breaker 5.

[0029] By setting the ground resistance meter 3, the ground resistance meter 3 is used to measure the resistance value. When the resistance value is abnormal, it indicates that the power distribution equipment is not grounded properly.

[0030] Please see Figure 4 The height adjustment mechanism 6 includes a threaded screw 601 rotatably installed inside the wall panel 7 of the power distribution room. A height adjustment block 602 is threaded onto the surface of the threaded screw 601 and is fixedly connected to the back of the insulating protective cover 1.

[0031] The height adjustment mechanism 6 is designed to adjust the insulating protective cover 1 to a high position in the power distribution room, preventing personnel from touching it and avoiding accidental contact or misoperation that could result in electric shock.

[0032] Please see Figure 4 A servo motor 8 is fixedly installed on the top surface of the wall panel 7 in the power distribution room, and the servo motor 8 is fixedly connected to the top of the threaded screw 601.

[0035] The limiting groove facilitates the sliding of the height adjustment block 602.

[0036] Please see Figure 2The edge of the front of the insulating protective cover 1 is hinged to a cover door 9, and a door lock is fixedly installed on the surface of the cover door 9.

[0037] The door 9 serves to open and close the insulating protective cover 1.

[0038] The model of the grounding resistance measuring instrument 3 is: Electric Explosion Network BT-001. The above models can be selected according to the actual situation.

[0039] Working steps: Install the power distribution equipment inside the insulating protective cover 1. The conductive sheet 2 and the grounding mechanism 4 ground the power distribution equipment. The grounding resistance measuring instrument 3 is used to measure the resistance value. When the resistance value is abnormal, it indicates that the power distribution equipment is not grounded properly. Then, the controller controls the circuit breaker 5 to close the circuit, so as to ensure that the power distribution equipment is well grounded and can cut off the power supply in time in case of abnormality, thus preventing electric shock accidents.

[0040] After the servo motor 8 is powered on, it drives the screw 601 to rotate, which in turn drives the height adjustment block 602 to rise and fall on the wall-mounted plate 7 of the power distribution room. When the power distribution equipment does not need to be operated, the insulating protective cover 1 is adjusted to a high position in the power distribution room, so that personnel cannot touch it, thus avoiding accidental contact or operation and electric shock.
