Problems solved by technology

[0003] When the electrical components inside the switchgear are in operation, a large amount of heat will be generated. In the prior art, the convection of the internal and external air is generally carried out through the heat dissipation holes to realize heat dissipation. As the heat continues to accumulate, it is prone to overheating safety hazards

Embodiment 1

[0038] see figure 1 , a power distribution cabinet with dynamic overheating warning, comprising a cabinet body 1, a cabinet door 2 is installed on the cabinet body 1, a plurality of evenly distributed heat dissipation windows 3 are fixedly inlaid on the side ends of the cabinet body 1, and the heat dissipation windows 3 are internally connected with A plurality of evenly distributed heat sink spacers 4 .

[0039] see Figure 2-3, two symmetrical electric push rods 5 and a tension sensor 10 are installed at the top of the heat dissipation window 3. The tension sensor 10 is located in the middle of the two electric push rods 5, and between the lower end of the electric push rod 5 and the plurality of heat sink spacers 4 Both are fixedly connected with a position control rope 6, a pull rope 11 is fixedly connected between the lower end of the tension sensor 10 and the middle of the uppermost heat sink spacer 4, and a self-resetting elastic switch 8 is electrically connected to t...

Embodiment 2

[0051] see Figure 8 , the photosphere 9 includes an outer layer 91, an inner light-emitting layer 92 located in the outer layer 91, and a plurality of uniformly distributed limit ropes 93 connected between the inner light-emitting layer 92 and the outer layer 91. The outer layer 91 and the inner light-emitting layer A plurality of counterweight moving balls 12 are placed between 92, the inner luminescent layer 92 is filled with fluorescent liquid and inert gas, the filling degree of the fluorescent liquid is not less than 60%, and the inner luminescent layer 92 is a transparent elastic structure with many protrusions on the outer surface. , when the light ball 9 moves along the thermally variable elastic bar 43, the internal counterweight moving ball 12 is in a dynamic state, which can generate a certain vibration force on the inner light-emitting layer 92, so that the internal fluorescent liquid is more affected The vibration of the emitted light makes the dynamic warning ef...

Abstract

The invention discloses an overheat dynamic early warning power distribution cabinet, which belongs to the field of power distribution cabinets, and is characterized in that through the arrangement of a plurality of heat sink division bars, the heat sink division bars firstly gather and move downwards after being overheated, so that a gap which is obviously increased is formed above a heat dissipation window; and meanwhile, in cooperation with the effect of an electric push rod, the process that the middle of the heat sinking division bar is continuously changed from downward deformation to upward protruding deformation and returns to the original position can be controlled, in the process, the light ball continuously moves back and forth in the heat sinking division bar, and the heat dissipation effect is improved. Compared with the prior art, after overheating, before a worker takes corresponding measures, the heat dissipation speed can be spontaneously increased, the speed of continuous temperature rising is effectively restrained, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the field of power distribution cabinets, and more particularly, to a power distribution cabinet with dynamic overheating early warning. Background technique [0002] The main function of switchgear is to open and close, control and protect electrical equipment in the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, isolating switches, load switches, operating mechanisms, transformers and various protection devices. There are many classification methods for switchgear. For example, the circuit breaker installation method can be divided into removable switchgear and fixed switchgear; or according to different cabinet structures, it can be divided into open switchgear, metal-enclosed switchgear, and metal switchgear. Closed armored switchgear; according to different voltage levels, it can be divided into...
