Technical field
The utility model relates to switch cubicle technical field, relates in particular to a kind of heat dissipation type low-tension switch cabinet.
Background technology
Low-tension switch cabinet is applicable to the industries such as power plant, oil, chemical industry, weaving, skyscraper, as the use of transmission of electricity, distribution and electric energy conversion.Along with the development of modernization industry, building industry and power industry, higher requirement be it is also proposed to the stuctures and properties of switch cubicle.Existing cabinet type mainly contains GGD, GCK, GCS, MNS etc.
As is known in the industry, the heating of low tension switch cabinet equipment has several factors, main has: the heating etc. that the heating that the heating that element runs, bus run, the heating of electric terminal, electromagnetic eddy cause, the rising of each inside switch cabinet temperature can affect the normal use of equipment component, even can cause the generation of fire.Existing low voltage switchgear all adopts the structure of sealing, and air permeability is poor, and cause heat to distribute slowly, the temperature in cabinet is always higher.In order to solve this technical problem, China Patent No. discloses a kind of draughty low-tension switch cabinet for the prior art of " 201220069586.3 " on October 3rd, 2012, this patent solves the problem of cabinet internal heat dissipating by arranging shutter and ventilation hole on cabinet.But in actual use, the radiating mode in this patent belongs to passive heat radiation, there is the defect of radiating effect difference.In addition, extraneous dust, impurity or worm ant etc. easily enter cabinet inside by shutter and ventilation hole, also will have a strong impact on the normal operation of switch cubicle.
Utility model content
The purpose of this utility model is to solve the above-mentioned problems in the prior art, provides a kind of heat dissipation type low-tension switch cabinet, and the technical problem that the utility model solves initiatively the hot-air in cabinet, dust and impurity to be expelled to outside cabinet.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of heat dissipation type low-tension switch cabinet, it is characterized in that: comprise cabinet, air exhauster, air draught arm, air draught house steward, described air draught house steward is vertically fixed in cabinet, the upper end closed of described air draught house steward, lower end is stretched out cabinet and is connected with the inlet scoop of air exhauster, described air draught arm evenly offers multiple inlet scoop that Open Side Down, and described air draught arm fixes on the inwall of cabinet, and the two ends of air draught arm all by Flange joint on air draught house steward.
The quantity of described air draught arm is three, and three air draught arms are separately positioned on the upper, middle and lower in cabinet.
Be provided with spherical filter room between described air exhauster and air draught house steward, described spherical filter indoor are provided with filter screen, and described spherical filter ball is connected with air exhauster and air draught house steward respectively by two flexible pipes.
Be provided with temperature detect switch (TDS) in described cabinet, described temperature detect switch (TDS) is connected the opening and closing for controlling air exhauster with air exhauster.
Employing the utility model has the advantage of:
One, in the utility model, by coordinating of air exhauster and air draught house steward and air draught arm, can initiatively the hot-air in cabinet be drawn to outside cabinet, such structure not only solves the high problem of temperature in cabinet, extraneous dust, impurity or worm ant etc. can also be avoided to enter cabinet inside, also help the useful life extending each equipment in switch cubicle simultaneously, effectively ensure the trouble-free operation of switch cubicle.In addition, Open Side Down the inlet scoop on air draught arm is arranged, and is not only conducive to reducing air-flow to the impact of cabinet inner cable equipment, also help by dead angle place year dust, impurity etc. in cabinet together sucking-off to outside cabinet.
Two, in the utility model, three air draught arms are separately positioned on the structure of the upper, middle and lower in cabinet, are conducive to the harmony ensureing temperature in upper, middle and lower three regions in cabinet.
Three, in the utility model, spherical filter room is connected with air exhauster and air draught house steward respectively by two flexible pipes, has both been conducive to fast assembling-disassembling spherical filter room, can have prevented again major diameter foreign matter from carrying out air exhauster.
Four, in the utility model, being achieved the automatic shutter of air exhauster by temperature detect switch (TDS), namely can the temperature in cabinet higher than automatically starting air exhauster during design temperature, cabinet being dispelled the heat by temperature switch.
