Embodiment 1

[0014] Embodiment 1: A multifunctional distribution box, including a box body, a high molecular polyethylene board is provided on the outside of the box body, and an elastic buffer device is provided between the high molecular polyethylene board and the outside of the box body, and the elastic buffer A pressure sensor, a trigger sensor and an alarm device are arranged between the buffer device and the high-molecular polyethylene board, and the high-molecular polyethylene board is sequentially covered with a strengthening layer, an insulating layer, a shielding layer and a waterproof layer.

Embodiment 2

[0015] Embodiment 2: A multifunctional distribution box, including a box body, a high molecular polyethylene board is provided on the outside of the box body, and an elastic buffer device is provided between the high molecular weight polyethylene board and the outside of the box body. A pressure sensor, a trigger sensor and an alarm device are arranged between the buffer device and the high-molecular polyethylene board, and the high-molecular polyethylene board is sequentially covered with a strengthening layer, an insulating layer, a shielding layer and a waterproof layer. The reinforcing layer is braided by high-tenacity polyester fiber and high-strength alloy fiber. The insulating layer comprises the following components by weight: 10-15 parts of high-density polyethylene, 15-20 parts of raw rubber, 2-5 parts of amine phosphate flame retardant, 1-3 parts of aluminum oxide powder, 2 parts of antioxidant ~4 parts, chromium oxide powder 5~10 parts. The shielding layer is made...

Embodiment 3

[0016] Embodiment 3: A multifunctional distribution box, the insulating layer includes the following components by weight: 12 parts of high-density polyethylene, 18 parts of raw rubber, 3 parts of amine phosphate flame retardant, and 2 parts of alumina powder , 3 parts of antioxidant, 8 parts of chromium oxide powder. The structure of the remaining parts is the same as in Embodiment 2.

[0017] In view of the above-mentioned embodiments, the present invention adopts various types of sensors and alarm devices, which can prevent the distribution box from being artificially destroyed, and can also avoid the problem of lack of effective monitoring when an unexpected situation occurs inside the distribution box. The use and function of the distribution box can be increased by adopting a multi-layer structure, and the function of the distribution box itself can be improved.

Abstract

The invention discloses a multifunctional power distribution box, and belongs to the field of the power distribution box and used for the power distribution box. The multifunctional power distribution box comprises a box body; a high molecular polyethylene plate is arranged outside the box body; an elastic buffer apparatus is arranged between the high molecular polyethylene plate and the outer side of the box body; a pressure sensor, a trigger sensor and an alarming apparatus are arranged between the elastic buffer apparatus and the high molecular polyethylene plate; and the high molecular polyethylene plate is covered with a reinforcing layer, an insulating layer, a shielding layer and a waterproof layer in sequence. By virtue of the technical scheme, the completeness monitoring of the power distribution box shell can be realized, external signals which influence precision instruments in the power distribution box can be shielded, and falling off or damage of an external layer anti-corrosion material also can be avoided.

Description

technical field [0001] The invention belongs to the field of distribution boxes, and in particular relates to a multifunctional distribution box. Background technique [0002] The distribution box is mainly responsible for the switch and control of the power grid. The traditional distribution box usually uses a metal shell, and the surface of the metal shell is coated with anti-corrosion materials to prolong the service life of the distribution box. However, in actual use, it is found that the anti-corrosion material of the outer layer is often damaged or cracks fall off, and the metal shell at the fall off or damaged part is severely corroded. Contents of the invention [0003] The purpose of the present invention is to provide a multi-functional distribution box, which can realize the monitoring of the integrity of the distribution box shell, and can also realize the shielding of signals affecting the precision instruments inside the distribution box from the outside, an...
