Abstract
The present utility model discloses a capacitance compensation box. An air vent (2) is arranged on a bottom plate (1) of a box body, a suction pump (3) is arranged inside the box body, an air suction opening of the suction pump (3) is arranged above the air vent (2) of the bottom plate (1), and an air exhaust opening (5) is arranged on a top plate (4) of the box body. The capacitance compensation box has ideal heat radiation effects.
Description
Technical field
The utility model relates to field of power, specifically is a kind of capacitance compensation box.
Background technology
The effect that reactive power compensating apparatus is born in the electronic power system is the power factor that improves electrical network, reduce the loss of supply transformer and conveying circuit, improve power supplying efficiency, improve the power supply environment, capacitance compensation box mainly is the casing of depositing this reactive power compensating apparatus.For the ease of heat radiation, the base plate of the casing of the capacitance compensation box of prior art is provided with blow vent, is coated with screen pack on the blow vent, but the radiating effect of this casing is still undesirable, and under summer high temperature environment, the temperature in the casing is still very high.
Summary of the invention
The technical problems to be solved in the utility model is to provide radiating effect very good a kind of capacitance compensation box.
Technical solution of the present utility model is, a kind of capacitance compensation box is provided, and the base plate of this casing is provided with blow vent, also is provided with aspiration pump in the casing, and the air entry of aspiration pump is positioned at the top of the blow vent of base plate, and the top board of casing is provided with exhaust outlet.
A kind of capacitance compensation box of the present utility model compared with prior art has the following advantages:
Under the effect of aspiration pump, gas enters from the blow vent of base plate, discharges from the exhaust outlet of top board, like this, can strengthen casing and extraneous cross-ventilation, so that the heat in the casing is dispersed into outside the casing by convection current, so radiating effect is very good.
As preferably, be equipped with screen pack on blow vent and the exhaust outlet, like this, can effectively reduce the dust, the impurity that enter in the casing.
Description of drawings
Fig. 1 is the positive sectional structure schematic diagram of a kind of capacitance compensation box of the utility model.
Shown in the figure 1, base plate, 2, blow vent, 3, aspiration pump, 4, top board, 5, exhaust outlet.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of capacitance compensation box of the utility model, the base plate 1 of this casing is provided with blow vent 2.Also be provided with aspiration pump 3 in the casing, aspiration pump 3 can be fixed on the base plate 1 or side plate of casing.The air entry of aspiration pump 3 is positioned at the top of the blow vent 2 of base plate 1.The top board 4 of casing is provided with exhaust outlet 5.Be equipped with screen pack on blow vent 2 and the exhaust outlet 5.
Claims (2)
