Description
Technical field
The present invention relates to high and low voltage switchgear field more particularly to a kind of dustproof and anti-explosion type high and low voltage switchgears.
Background technique
Switchgear is the device for receiving and distributing electric energy in electric system, and switchgear outside line is introduced into master control in cabinet and opens the light,
Subsequently into sub-control switch, each branch is set according to its needs.It has the function of the cabinet for being controlled circuit, being protected and being detected
Body is mainly used for the places such as power plant, substation.
Generally switchgear is adopted closed, and switchgear generates a large amount of heat at work, and heat assembles meeting so that internal temperature
Degree increases, so that heat is spread out, influences the service life of switchgear.In order to distribute the heat of aggregation, usually
One radiator or fan are installed in switchgear bottom, and in actual use, extraneous dust and worm fly easily pass through
Inside radiator fan access switch cabinet, the cleaning inside of switchgear is not only influenced in this way, but also even will affect switchgear sometimes
Normal use.There is the setting of some switchgears more complicated in such as mine lamp environment, there are flammable explosive gas or more in environment
In the environment of dust, this environment makes switchgear be easier to accumulate dust, or even explodes.But it is current market sales of
It can be good at handling the device of accumulation volume dust and its internal dust in switchgear there is no setting.
In the patent that the patent name that notification number is CN205609966U is a kind of high anti-dust performance high and low voltage switchgear
It is by the way that depositing dust dedusting mechanism is arranged in air inlet, depositing dust dedusting mechanism is successively arranged safety guard net, coarse filtration from inside to outside
Net, activated carbon interlayer and electrostatic precipitation net considerably increase it in the contact area of air inlet by the way that coarse strainer is arranged, thus
The dedusting area on fixed unit area is improved, is dusted operation convenient for depositing dust dedusting mechanism, but its depositing dust dust removal machine
Structure is complicated for structure, at high cost, the not reproducible use of activated carbon interlayer therein, and it does not have explosion-proof function.
It is a kind of ventilation explosion-proof type high and low voltage switchgear and its anti-corrosion in the patent name that notification number is CN105207069A
Be in the patent of technique by the upper surface of cabinet body be arranged venting, and by the opening of venting be arranged threat face, explosion-proof
The mode that explosion-proof lid is covered on mouth carries out technological processing for explosion protection feature, and this mode can timely prevent switchgear by way of decompression
Explosion caused by internal pressure is excessive, but it can not play a protective role in explosion time, while it does not have dust-proof resistance dirt
It acts on, is easy for being infected with dust, the serious use for influencing other control units on other control units in switchgear
Service life.
