Problems solved by technology

[0003] The existing power distribution device is located in a complex environment, with many internal circuits, and the internal circuit is prone to aging or short circuit caused by moisture, which will cause certain harm to people's lives and property safety; the existing power distribution device does not have fire protection function , when a fire source is generated in the power distribution device, it cannot be extinguished in time, which further expands the fire. Therefore, it is necessary to improve the power distribution device to solve the above problems

Embodiment 1

[0023] Please refer to the figure, in an embodiment of the present invention, a power distribution device with a fireproof function includes a cabinet 1, a base 2, a top plate 3 and a rain shield 4; a cabinet door is arranged on the front of the cabinet 1, and the cabinet The body 1 is fixed on the upper surface of the horizontal base 2, and the device is fixed through the base 2. On the side wall of the base 2, there is an inlet pipe 23, and the inlet pipe 23 extends into the base 2 and connects upward with the cabinet body 1. Internal communication, so that the incoming and outgoing lines in the power distribution device enter the cabinet 1 from the bottom of the base 2; the top plate 3 is fixedly installed on the top of the cabinet 1, and the area of ​​the top plate 3 is larger than the cross section of the cabinet 1 Covering the top of the cabinet body 1, a rain shield 4 is fixed on the outer wall of the top plate 3 to protect the power distribution device.

Embodiment 2

[0028] On the basis of Embodiment 1, a fire extinguisher 8 is arranged in the storage box 7, and the fire extinguisher 8 is communicated with a pipeline 9 extending into the bottom of the top plate 3, and a solenoid valve 10 is installed on the pipeline 9, and the solenoid valve 10 according to The position of the counterweight ring 5 is linked and controlled. When the counterweight ring 5 is put down, the solenoid valve 10 is opened, and the fire extinguishing gas in the fire extinguishing tank 8 is sprayed into the bottom of the top plate 3 to extinguish the fire below.

[0029] There are two fire control methods for power distribution devices. One is to detect through the internal smoke sensor 22. When a fire source occurs, the smoke sensor 22 detects smoke and transmits the detection signal to the controller 11. 11 Control the clamping head 16 to loosen, so that the counterweight ring 5 is lowered, so that the cabinet body 1 is wrapped under the fire curtain 6 to prevent th...

Abstract

The invention relates to the field of power, and particularly discloses a power distribution device with a fireproof function. The device comprises a cabinet body, a base, a top plate and a rain baffle; a counterweight ring horizontally surrounding the outer side of the cabinet body is arranged below the top plate, a fireproof curtain is fixedly arranged on the counter weight ring, the counterweight ring and the top plate are connected through a pull rope, and the upper end of the pull rope is clamped through a clamping head installed on the top plate; and the top of the cabinet body is fixedly provided with a heat conduction rod extending into the cabinet body, and the pull rope is wound on the heat conduction rod. Through the fireproof curtain connected to the counterweight ring, the counterweight ring falls down when the interior is on fire, the fireproof curtain covers the outer side of the cabinet body, connection with the outside is blocked, external air is prevented from entering the interior, and the internal fire behavior is controlled; and the counterweight ring is controlled to fall through the clamping head and the heat conducting rod, so that a complementary effect is achieved, and the fireproof function of the power distribution device is ensured.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a power distribution device with a fire prevention function. Background technique [0002] With the development of social economy and the acceleration of industrialization, the development of electric power is becoming more and more rapid. Power distribution devices have become more and more popular in life. As the main switchgear of cable networks, power distribution devices are mostly used in industrial parks and residential communities. and business centers. [0003] The existing power distribution device is located in a complex environment, with many internal circuits, and the internal circuit is prone to aging or short circuit caused by moisture, which will cause certain harm to people's lives and property safety; the existing power distribution device does not have fire protection function , When a fire source is generated in the power distribution device, it cannot be exting...
