Abstract
The utility model provides a kind of transformer Ventilation Control case, comprise the casing with protecgulum, the top cover of described casing is provided with ventilation hole, ventilation hole internal fixtion has ventilating fan, the both sides of lower box are provided with ventilation duct, in ventilation duct, be provided with Air Filter, described ventilation duct is L shape bend pipe, and Open Side Down.The control cabinet of the program has ventilating fan, can promote casing inner air flow, and then solves control cabinet over-heat inside element burnout problems, thus improves equipment up-time efficiency and operation of power networks reliability.
Description
Technical field
The utility model relates to a kind of transformer control cabinet, especially a kind of transformer Ventilation Control case that can regulate heat radiation.
Background technology
In the prior art, the important component part of known technology to be power transformer be transformer station and electrical network, its operation conditions is directly connected to the stable of electrical network and safety, therefore transformer control cabinet is also particularly important, and present transformer control cabinet is placed on outdoor mostly, long by the solar radiation time, long-time running inner member generates heat and causes temperature rising, acceleration components is aging even burns, and causes equipment irregular operating, reduces equipment and operation of power networks reliability.This is the weak point existing for prior art.
Summary of the invention
The purpose of this utility model, be exactly for the deficiency existing for prior art, and a kind of technical scheme of transformer Ventilation Control case is provided, the control cabinet of the program can solve control cabinet over-heat inside element burnout problems, thus improves equipment up-time efficiency and operation of power networks reliability.
This programme is achieved by the following technical measures: a kind of transformer Ventilation Control case, comprise the casing with protecgulum, the feature of this programme is: on the top cover of described casing, be provided with ventilation hole, ventilation hole internal fixtion has ventilating fan, the both sides of lower box are provided with ventilation duct, in ventilation duct, be provided with Air Filter, described ventilation duct is L shape bend pipe, and Open Side Down.
Described ventilation hole is two.
Described top cover is inverted V-shaped.
Have the temperature controller of a control ventilating fan job, the output of temperature controller is connected with a relay, and the normally opened contact of relay is connected with ventilating fan.
Described ventilating fan is three-phase ventilating fan.
Described ventilation duct is fixed on casing by flange.
The beneficial effect of this programme can be learnt according to describing of such scheme, owing to having ventilation hole and ventilation duct in this scenario, backflow can be formed, when control cabinet works, its inner heat produced can rise, flowed out by ventilating opening, cold air can enter control cabinet by ventilation duct, forms backflow, when temperature controller detects that temperature is too high, ventilating fan work can be controlled, accelerate air circulation, promote cooling in control cabinet; Ventilating fan is two, namely can not destroy the bulk strength of box cover, is also beneficial to the circulation carrying out air; Ventilation duct is L shape bend pipe, and Open Side Down, is conducive to air like this and enters ventilation duct, rainwater etc. can also be avoided to enter casing and damage element; In ventilation duct, be provided with Air Filter, dust and insect etc. can be avoided to enter casing, reduce the useful life of element; Top cover is V-arrangement, is conducive to the landing of rainwater etc., avoids rainwater etc. to flow into casing; Ventilation duct is fixed on casing by flange, adds fastness.As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent.
