Abstract
The utility model relates to a self -circulation heat dissipation switchgear. The purpose is that the switchgear who provides should have self -loopa heat dissipation function to have that the operation is reliable, simple structure, the lower characteristics of cost. Technical scheme is: a self -circulation heat dissipation switchgear, is including the cable chamber, circuit breaker room and the bus -bar room that set up in the casing and formed by the baffle, this switchgear of its characterized in that still is provided with self -loopa cooling system, the airflow channel who has a determining deviation that this self -loopa cooling system includes between cable chamber and the casing, formed by the baffle between cable chamber and the circuit breaker room, between cable chamber and the bus -bar room, between circuit breaker room and the bus -bar room and respectively, and airflow channel's one end is as the front of air intake setting at switchgear, and the other end is as the top of discharge port setting at switchgear.
Description
Technical field
The utility model relates to a kind of power switchgear, is especially furnished with miniaturization and the intellectualized switchgear of self-circulation cooling system.
Background technology
Along with the development of Created in China, middle pressure series power switchgear domesticizes substantially, and processing performance constantly innovates upgrading.Traditional switchgear is because of process technology limit such as heat radiation, insulating material, and volume is large and heavy; After adopting the design of new processes after improving, switchgear volume is more miniaturized, obviously has new requirement to circulation cooling.Thus, design a kind of switchgear with self-loopa heat sinking function, guarantee that equipment is reliable, has realistic meaning.
Utility model content
The object of the utility model patent is to provide a kind of middle pressure series switch equipment of modified node method, and this switchgear should have self-loopa heat sinking function, and have reliable, structure is simple, lower-cost feature.
The technical solution adopted in the utility model is as follows:
A kind of self-loopa heat dissipation switch equipment, comprises cable vault that setting formed in the housing and by dividing plate, breaker chamber and bus-bar room; It is characterized in that this switchgear is also provided with self-circulation cooling system, this self-circulation cooling system to comprise between cable vault and housing, between cable vault and breaker chamber, between cable vault and bus-bar room, between breaker chamber and bus-bar room and the tool gas channel at regular intervals formed by dividing plate respectively, one end of gas channel is arranged on the front of switchgear as air inlet, the other end is arranged on the top of switchgear as outlet.
Described cable vault, breaker chamber and bus-bar room are also manufactured with the blow vent being communicated with gas channel.
A described determining deviation is 5-30mm.
Described cable vault, breaker chamber are also shaped with the air inlet being positioned at switchgear front respectively.
Described air inlet is screened by perforated baffle.
Operation principle of the present utility model is:
In switchgear after the heating of energising components and parts, hot gas is discharged toward the self-loopa hot gas outlet on cabinet top by the gas channel in switch cubicle, three, the upper, middle and lower air inlet (air inlet) of the self-circulation cooling system of Simultaneous Switching equipment enters cool exterior air fast, makes heater element lower the temperature fast.
The beneficial effects of the utility model are:
Owing to being configured with self-circulation cooling system, heat dispersion is greatly improved, and equipment runs more reliable, and thus the miniaturization of switchgear volume is effectively ensured; In addition, the utility model structural modification is simple, and thus cost is lower, has popularity prospect.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model.
Fig. 2 is the partial portion structure for amplifying schematic diagram in Fig. 1.
Embodiment
Further illustrate below in conjunction with embodiment shown in the drawings.
Self-loopa heat dissipation switch equipment shown in the drawings, comprises cable vault that setting formed in the housing and by dividing plate, breaker chamber and bus-bar room; These and conventional switchgear are roughly the same.
Improvement of the present utility model, be provided with self-circulation cooling system on this switchgear, this self-circulation cooling system comprises the tool formed by dividing plate respectively between cable vault and housing, between cable vault and breaker chamber, between cable vault and bus-bar room, between breaker chamber and bus-bar room gas channel at regular intervals, one end of gas channel is arranged on the front of switchgear as air inlet, the other end arranges the top of switchgear as outlet; That is, described dividing plate is double-layer clapboard, and the spacing between double-layer clapboard is as the passage (also forming gas channel between dividing plate and housing) of circulated gases; Such as, the gas channel between cable vault and breaker chamber, is formed (the rest may be inferred by analogy for it, no longer repeats) by the cable vault's dividing plate kept at a certain distance away and breaker chamber dividing plate.A described determining deviation can be determined as required, is recommended as 5-30mm.
Visible in figure: described air inlet 1 is positioned at the front (air inlet is provided with perforated baffle, enters to stop toy) of switchgear; Also can determine separately as required.
Further, described cable vault, breaker chamber and bus-bar room are also manufactured with the blow vent being communicated with gas channel; Breaker chamber blow vent 2, cable vault's blow vent 3 and bus-bar room blow vent 4 is respectively illustrated in figure.
Described cable vault, breaker chamber are also shaped with the air inlet being positioned at switchgear front respectively; Cable vault's air inlet 5, breaker chamber air inlet 6 is respectively illustrated in figure.
Described air inlet is provided with perforated baffle; Opening on perforated baffle is shaped with multiple air-vents of diameter 3-5mm, enters to stop toy.These air-vents also can be screened by decorative panel, except lower decorative panel when enabling.
