Abstract
An armored metal enclosed switchgear having an excellent fan heat radiation structure is a cabinet. The cabinet is mainly divided into compartments including a parent part compartment (4), a cable compartment (5), an accessory compartment (7) and a breaker compartment (8), a heat radiation fan (1) is equipped on a support (2) included in accessories; the separator plates of the compartments, and panels, bottom plates and side plates of the cabinet are provided with through holes (3); the support (2) or the cabinet is provided with at least two groups of mounting screws. When the heat radiation fan blasts air, the air may come from the accessory compartment (7) to the cable compartment (5), the breaker compartment (8), a handcart compartment and the parent part compartment (4), and then to outside of the cabinet, thus forming excellent ventilation circulation channels and accelerating the air convection; the convection occurs in a switch compartment, the cable compartment (5) and the parent part compartment (4), as well as pressure release channels thereof, the heat radiation situation in the equipment is improved, and the normal operation of the equipment is realized.
Description
Technical field
The utility model relates to the radiator structure of armored metal enclosed switchgear, especially relates to a kind of big electric current (≤4000A) armored metal enclosed switchgear.
Background technology
The present armored metal enclosed switchgear cabinet of producing, mainly can be divided into compartments such as bus-bar room, cable vault, handcart chamber, annex chamber, breaker chamber in the cabinet, exhausting is carried out at the top that generally all is contained in the switch cubicle bus-bar room for the blower fan of heat transmission, make air outside bus-bar room is extracted into cabinet, carry out forced flow from the cable vault, to quicken air flows in the cabinet, reach the purpose of quickening heat radiation.But blower fan is installed in the top of switch cubicle bus-bar room, and adopts general axial flow blower, because of each compartment relative closure, so the convection current route only is cable vault and bus-bar room; Because breaker chamber also is that a big pyrotoxin and air flows performance are relatively poor relatively, radiating effect can not be satisfied the demand and be caused the equipment temperature rise to exceed standard sometimes, and equipment can not normally move.
The utility model content
The purpose of this utility model is to provide a kind of armored metal enclosed switchgear with good blower fan radiator structure, and its blower fan radiating effect can satisfy the needs of the normal operation of equipment fully.
Above-mentioned purpose can be achieved by the following technical programs: the armored metal enclosed switchgear with good blower fan radiator structure of the present utility model is a cabinet, mainly can be divided into compartments such as parent part chamber, cable vault, handcart chamber, annex chamber, breaker chamber in the cabinet, cabinet is equipped with cooling fan, it is characterized in that: described cooling fan is contained on the support in the annex chamber, and described support can be adjusted angle by screw is installed; Have through hole on the dividing plate of the dividing plate of described each compartment, the panel of cabinet, base plate, side plate and each compartment.
So when the cooling fan air blast, wind can be from annex chamber to cable vault, breaker chamber, handcart chamber, bus-bar room be at last outside cabinet, form a good ventilation circulation canal, quicken the convection current of air, the enhancing radiating effect satisfies equipment and normally moves (temperature rise does not exceed standard).
The beneficial effects of the utility model are: quickened the convection current of air, allow convection current occur in switch gear room, cable vault and parent part chamber and pressure release passage place separately thereof, heat radiation situation in the equipment will well be improved, and can satisfy the normal operation of armored metal enclosed switchgear.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that the structure of original switch cubicle and sink flows are to schematic diagram.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is that the structure of this novel switched cabinet and sink flows are to schematic diagram.
Fig. 4 is the left view of Fig. 3.
Fig. 5 is a cabinet panel cut out schematic diagram.
Fig. 6 is a cabinet breaker chamber bottom panel perforate schematic diagram.
Among the figure: 1. cooling fan, 2. support, 3. through hole, 4. parent part chamber, 5. cable vault, 6. handcart chamber, 7. annex chamber, 8. breaker chamber.
Embodiment
As shown in Figures 1 and 2, the cooling fan 1 of former switch cubicle heat transmission is contained in the top of switch cubicle parent part chamber 4, air flow only from the cable vault 5 to parent part chamber 4 to outdoor, radiating effect can not be satisfied the demand, the equipment temperature rise of causing exceeds standard, equipment can not normally move.
Fig. 3 is to shown in Figure 6 the novel armored metal enclosed switchgear with good blower fan radiator structure, mainly can be divided into parent part chamber 4 in the cabinet, cable vault 5, handcart chamber 6, annex chamber 7, breaker chamber 8 compartments such as grade, cooling fan 1 is installed on the support 2 of 8 times department enclosure chambers 7, preceding cabinet breaker chamber of equipment, support 2 usefulness 2-M6X20 screw are installed on the side plate of the preceding cabinet of the mid-handcart cabinet of withdraw-type, in order to supporting cooling fan 1, have many groups on support 2 or the cabinet screw is installed, this example is to have four groups screw is installed on the side plate of preceding cabinet, so that the angle useable holder 2 of cooling fan 1 air outlet is adjusted arbitrarily; The dividing plate of each compartment, the panel of cabinet, base plate, have through hole 3 on the dividing plate of side plate and each compartment, the door of the annex chamber 7 that this is routine, the dividing plate that switch gear room and annex chamber are 7, have the through hole that satisfies the IP2X degree of protection 3 of some on the dividing plate that cable vault 5 and parent part chamber are 4, allow the switch gear room, annex chamber 7, cable vault 5, parent part chamber 4 and equipment connect outward, can reach the purpose that increases the convection current route like this, produce convection current route as Fig. 3, increase breaker chamber 8, the convection current of the air of cable vault 5, strengthen the convection intensity of parent part chamber 4, strengthen radiating capacity of equipment, satisfied the normal service requirement of product.
Claims (2)
1. armored metal enclosed switchgear with good blower fan radiator structure, shape is a cabinet, mainly can be divided into parent part chamber (4), cable vault (5), handcart chamber (6), annex chamber (7), breaker chamber compartments such as (8) in the cabinet, cabinet is equipped with cooling fan (1), it is characterized in that: described cooling fan (1) is contained on the support (2) in the annex chamber; Have through hole (3) on the dividing plate of the dividing plate of described each compartment, the panel of cabinet, base plate, side plate and each compartment.
2. the armored metal enclosed switchgear with good blower fan radiator structure according to claim 1 is characterized in that: the installation screw that has at least two pack supports (2) on described support (2) or the cabinet.
