Description
Technical Field
The invention relates to the technical field of power distribution equipment, in particular to an outdoor electrical equipment protection cabinet based on commercial power transmission.
Background
In the distribution of commercial power, a distribution box is generally used, the distribution box is a mass parameter on data, generally, a low-voltage forest is formed according to electrical wiring, and switching equipment, a measuring instrument, a protective electrical appliance and auxiliary equipment are required to be assembled in a closed or semi-closed metal cabinet or on a screen to form the low-voltage distribution box, and a circuit can be switched on or switched off by a manual or automatic switch in normal operation.
Most of the block terminals all set up outdoors, in order to make things convenient for the workman to maintain it, in order to avoid rainy day's rainwater and moisture to get into the inside of block terminal, present block terminal all sets up to the box that can seal, but in hot summer, resident's power consumption increases, the block terminal is under high load operation or sun's irradiation, can lead to its inside temperature to rise fast, and seal structure's box makes the radiating efficiency of block terminal lower, thereby lead to the inside accessories of block terminal to damage because of high temperature easily, influence the life of block terminal, therefore we propose a block terminal with the dampproofing function of cooling to solve above-mentioned problem.
For example, patent nos.: CN201710660522.8 discloses a distribution box with damp-proof, heat-dissipation and ventilation functions, and aims to solve the technical problem that' the distribution box is easy to be wetted by water entering, so that equipment in the distribution box is influenced; when the rainwater detection sensor senses rainwater, the lifting seat moves upwards, the rotary disc rotates, the water receiving disc on the rotary disc is aligned with the round hole of the box cover, and the water receiving disc can dissipate heat inside the distribution box through the rainwater, the application can achieve the effect of damp-proof heat dissipation through the recorded content of the specification, but in hot summer and when weak light rain just begins in the sky, the rainwater detection sensor can instantly control the screw rod to rotate when detecting the rainwater, make the lifting seat rise and the carousel rotates, it is corresponding with the round hole on the case lid to make the water receiving disc on the carousel, thereby make fan stop work, utilize the rainwater to dispel the heat to the block terminal, at this moment because just begin to rain, ambient temperature does not reduce in the twinkling of an eye because of the rainwater, and owing to be little rain, the rainwater quantity that leads to the water receiving disc to receive is less, consequently, can make the radiating effect of this block terminal relatively poor, lead to the inside temperature of block terminal to rise in the twinkling of an eye, thereby lead to inside accessories can be burnt out by high temperature, influence its life.
For another example, patent nos.: CN201710987084.6 discloses dampproofing high voltage distribution cabinet convenient to heat dissipation, its technical problem that solve is that the switch board can not in time dispel the heat and lead to the damage of components and parts in the switch board very easily, and on overcast and rainy day, contain a large amount of moisture in the air and cause the internal component to damage easily, through setting up updraft ventilator in this application, first ventiduct and second ventiduct, utilize the wind of nature to drive updraft ventilator and carry out work, thereby take out the inside steam of block terminal, but not all can wind production every day, if hot summer, and do not have the wind flow one day, the heat that inside heat of block terminal and sun irradiation produced, can lead to the inside accessories of block terminal because high temperature damages, lead to its life to reduce.
