Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to an outdoor power distribution cabinet with a wire protection function. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet, which is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is suitable for occasions with relatively dispersed loads and fewer circuits; the motor control center is used for occasions with concentrated loads and more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This set of equipment should provide protection, monitoring and control for the load. The distribution cabinet is divided into primary, secondary and final levels. The primary distribution equipment is collectively referred to as the power distribution center. They are centrally installed in the enterprise's substation to distribute power to the lower-level distribution equipment in different locations. This level of equipment is close to the step-down transformer, so the electrical parameters are required to be higher and the output circuit capacity is also larger; the secondary distribution equipment is a general term for power distribution cabinets and motor control centers. The power distribution cabinet is suitable for occasions with relatively dispersed loads and fewer circuits; the motor control center is used for occasions with concentrated loads and more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load; the final distribution equipment is collectively referred to as the lighting power distribution box. They are far away from the power supply center and are decentralized small-capacity distribution equipment.

[0003] Most of the distribution cabinets on the market today are only devices for organizing lines. However, because the distribution cabinets are exposed to wind and rain outdoors, as well as factors such as animal and human activities, the wires outside the distribution cabinets are sometimes pulled, causing wear and tear on the wires, leading to the risk of leakage. Utility Model Content

[0004] The purpose of the utility model is to provide an outdoor power distribution cabinet with a wire protection function to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: an outdoor power distribution cabinet with a wire protection function, comprising a cabinet body, a wire winding device is arranged inside the cabinet body, and an anti-wear device is arranged inside and at the bottom of the cabinet body, and the wire winding device comprises:

[0012] Compared with the prior art, the utility model provides an outdoor power distribution cabinet with wire protection function, which has the following beneficial effects:

[0013] 1. For the outdoor power distribution cabinet with wire protection function, the wire enters the wire box from wire hole 2, then enters the shaft rod through wire groove 2, enters the wire reel after coming out from wire groove 1 in the shaft rod, passes through wire hole 3 and starts to wind several circles on the surface of the wire reel, and after winding, the wire comes out from wire hole 1 and goes out from the anti-wear device. When the wire is pulled externally, the wire will drive the wire reel to rotate in the wire box with the shaft rod as the axis, and the rotation of the wire box will drive the scroll spring inside to tighten, and then when the external pulling force disappears, the wire will be retracted to its original position, so as to prevent animals or people from accidentally driving the wire, pulling the wire, and causing no damage to the power distribution cabinet due to pulling force.

[0014] 2. For the outdoor power distribution cabinet with wire protection function, after the wire passes through the anti-wear device, if the wire is pulled outside, the two clamps will slide along with the wire in the direction of the pulling force, and at the same time the baffle will block the through hole caused by the sliding of the clamp. Then when the pulling force disappears, the wire will return to its original position due to the action of the spring, and rubber pads are installed where the clamp contacts the wire, which will not cause wear on the surface of the wire.
