Abstract
The utility model discloses a ventilation and heat dissipation device for electric switch equipment, which is characterized in that the ventilation and heat dissipation device for the electric switch equipment comprises a middle separator board, a fixed ventilation plate, a movable baffle plate, switch equipment. The middle separator board is arranged in the middle of an air inlet of the middle separator board, a lower sealing plate of the middle separator board, a bending plate of the middle separator board, the front-end opening hole of the middle separator board and the switch equipment; a cable chamber and a circuit breaker can be completely separated by the middle separator; the front end of the middle separator board is provided with a small rectangular air inlet of the middle separator board; and an air box of the middle separator board is divided into two air chambers by the fixed ventilation plate and the movable baffle plate. With the adoption of the scheme, directional air beam can be formed, and the heat dissipation efficiency is good; in addition, the personal security of the cable chamber and in the front of the cabinet cannot be affected when the pressure is released.
Description
Technical field
The utility model relates to electric switchgear assembly device, refers to intermediate switchgear cabinet ventilation cooling device especially.
Background technology
Existing domestic the most frequently used switchgear such as KYN28A-12 (Z) armored withdraw type ac metal closing switch gear (hereinafter to be referred as switchgear) are a kind of switchgears of technology maturation, and it extensively applies to fields such as power plant, chemical industry, mineral products, hospital.The circuit breaker mounting means is a middle, circuit breaker contact up and down connects main bus bar and lower end branch bar respectively, bus is because long-term galvanization can produce a large amount of heats, especially big electric current (rated current 2500A and more than) switchgear, bad if dispel the heat, the switch cubicle insulation life is shortened, influence personal safety when serious, therefore be necessary to introduce heat abstractor.
What general manufacturer adopted is that perforate is dispelled the heat on mid-cabinet central dividing plate, air communication is crossed the cable vault and is flowed to breaker chamber and come the circuit breaker natural cooling, its shortcoming is to lack fixing heat dissipation channel on the one hand, and the cable vault generally seals, and is not fine so cause its radiating effect; On the other hand because cable vault and breaker chamber connection are influential to the cable vault when the breaker chamber pressure release.
Summary of the invention
Defective at prior art, it is a kind of under the prerequisite that does not influence the switchgear outward appearance that the purpose of this utility model is to provide, the fine directed ventilation unit that cooperates with switchgear of energy, this device can form directed wind bundle, radiating effect is good, and when pressure release, do not influence the preceding personal safety of cable vault and cabinet again.
The purpose of this utility model is to realize by such technical scheme: a kind of electric switch equipment heat abstractor, it is characterized in that: comprise median septum, fixedly ventilating board, sideboard, switchgear, the median septum air inlet, shrouding under the median septum, the median septum bent plate, the perforate of median septum front end, median septum is installed in the middle of the switchgear, median septum can separate cable vault and breaker chamber fully, the median septum front end has small rectangle median septum air inlet, and fixedly ventilating board separates into two air chambers with sideboard with the median septum gas tank.
Further improve as above-mentioned execution mode, described fixedly ventilating board will have certain gradient, and its ventilating opening is less than the area of sideboard.
Further improve as above-mentioned execution mode, perpendicular to median septum, the width of sideboard is less than the air chamber height under the self gravitation effect for described sideboard, and length is less than air chamber length, and can rotate flexibly when air communication is crossed.
When the breaker chamber internal fault takes place when, air-flow is opposite with airflow direction among Fig. 2, pass through the perforate of median septum front end by breaker chamber, flow to gas tank, and sideboard angle of meeting rotation under the effect of air-flow cooperate shrouding of composition that air chamber 41 and 42 is isolated with mounting plate, so just can not influence the preceding personal safety of cabinet.
The beneficial effects of the utility model are: switchgear is when moving, and the wind before the cabinet is by directed vent passages through the median septum air inlet, and forming can be to the wind bundle that spreads all around, and the wind bundle dispels the heat to bus by air chamber, and radiating effect is good; Sideboard and fixedly ventilating board internal fault electric arc can be separated effectively, can not impact cable vault and personal safety.
Description of drawings
Fig. 1 is the schematic diagram in application of the present utility model.
Fig. 2 is an A part enlarged diagram among Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and instantiation.
With reference to Fig. 1,2, added shrouding 13 and median septum swash plate 14 under the median septum on the former basis of the utility model, when making the breaker chamber pressure release, be unlikely to influence the cable vault.And after adding above-mentioned two plates, provide fixedly wind bundle to heat dissipation channel.Because the median septum front end has perforate 15, so when internal fault appears in breaker chamber, powerful air-flow in Fig. 1 by breaker chamber 43 by perforate 15 to median septum air chamber 42 (41), at last by air inlet 12, the same like this personal safety that might jeopardize personnel before the cabinet.Therefore introduce fixedly ventilating board 2 and sideboard 3,
Fixedly ventilating board 2 is divided into 42 and 41 two parts with the median septum air chamber, fixing angle of ventilating board 2 first bendings, tilt to be installed on shrouding 13 centres under the median septum then, the angle of inclination is 45 °, ventilating opening 11 is fixedly arranged on the ventilating board, and ventilating opening forms air intake passage 41 with median septum air inlet 12; Sideboard 3 is installed in fixedly the ventilating board upper end, and sideboard 3 and median septum bent plate form air-out passage 42, and sideboard 3 can freely rotate along it, and can with the fixing swash plate of a sealing of ventilating board 2 compositions, gas tank 41 and 42 is separated fully.
