Abstract
The utility model discloses a double-layer dustproof moistureproof terminal box which comprises a box cap, an upper box body, a lower box body and a base. A first moistureproof layer is arranged between the upper box body and the lower box body; a second moistureproof layer is arranged between the lower box body and the base; the front surface and the back surface of the upper box body are respectively provided with an upper box body protection door; and the two side surfaces of the lower box body are respectively provided with a ventilation opening. The box cap and the upper box body are in sealing state, thereby enhancing the dustproof effect. The terminal box utilizes the double moistureproof layers to separate the upper box body, the lower box body and the base respectively, so that effective isolation and moistureproof effects are achieved; and a conventional single-layer blocking mode is abandoned, and a double-layer blocking mode is utilized, thereby greatly reducing moisture entrance amount, and guaranteeing safety work of terminal connection inside the box.
Description
Technical field
The utility model relates to a kind of double-deck dust and moisture terminal box, belongs to the technical field of electricity substation equipment.
Background technology
Terminal box of transformer substation is outdoor electrical equipment and the intermediate link of indoor observing and controlling, protection, the equipment connection such as communicate by letter, and is generally arranged on by primary equipment on the spot.When there was dampness in the air, especially in rainy season, moist condensation accumulated water in outdoor terminal box, easily causes the insulation against ground of direct-current secondary loop to decline, and severe patient insulation resistance drops to zero, thereby forms DC positive power or negative supply ground connection.If cause DC earthing, likely cause DC insurance fusing, protection tripping or malfunction, serious threat electric power netting safe running and employee's life security.Therefore the double-deck dust and moisture terminal box of development of new, is conducive to protect power equipment, reduces interruption duration, guarantees power supply continuation, increases electricity sales amount, improves Business Economic Benefit.At present, the terminal box of transformer station all adopts the shutoff of clay individual layer, and body structure is unreasonable, and heater improper use, so terminal box is easy to make moist.The feature of clay is: when moisture is many, and easy hot mastication; When moisture is few, easily hot cracking, produces gap.In addition, teams and groups' jurisdiction terminal box of transformer substation heater is all arranged on below, because terminal box space is little, heater is near near shutoff clay, causes clay be full of cracks, and shutoff is not tight; If heater is arranged on to top, near secondary cable, long-term baking will cause cable skin aging, and insulation reduces, and produces hidden danger.Moreover, the at present structure of the terminal box of transformer substation dehumidifying of all cannot effectively preventing dust.
Summary of the invention
For the deficiencies in the prior art, the utility model provides double-deck dust and moisture terminal box.This terminal box can effectively prevent that terminal box is subject to cargo sweat, when bringing safety benefit and economic benefit, has also greatly improved operating efficiency.
The technical solution of the utility model is as follows:
A double-deck dust and moisture terminal box, comprises case cap, upper box, lower box and base; Between described upper box and lower box, be provided with the first damp-proof layer, between described lower box and base, be provided with the second damp-proof layer: at described upper box front and back, be respectively arranged with upper box protective door; Two sides at described lower box are provided with ventilating opening.Case cap of the present utility model and upper box are sealing state, increase dust-proof effect.
Preferred according to the utility model, described the first damp-proof layer is complex waterproof layer, and the second damp-proof layer is marine glue mud layer; Described complex waterproof layer comprises that skin is coated with the plastic foam layer of clay.The advantage of design is herein, and the first damp-proof layer is further improved, and to setting up plastic foam layer in clay, stops terminal box bottom moisture and spreads in upper box, guarantees that moisture sheds in time along the ventilating opening of described lower box.
Preferred according to the utility model, described upper box and lower box are rectangular box.
The utility model is preferred, in the front of described lower box, is provided with lower box protective door.
The utility model is preferred, and the height of described lower box is 180-240mm.
Excellent results of the present utility model is:
Between terminal box case cap of the present utility model and upper box, no longer leave air outlet, effectively stop dust to enter terminal box inside.The utility model adopts double-deck damp-proof layer, and described upper box, lower box and base are cut off respectively, and effectively isolation is moistureproof, and the individual layer shutoff mode of abandoning tradition is used the mode of double-deck shutoff, greatly reduces moisture infiltration capacity.As shown in Figure 1, existing terminal box moisture enters in casing from terminal box bottom, is deposited in case and cannot gets rid of.And this new technique scheme, adopt double-deck plugging structure, first moisture intercepted by the second damp-proof layer of bottom, even if moisture enters in described lower box on a small quantity, moisture also can shed in time along the ventilating opening of described lower box both sides, recycle the first damp-proof layer and effectively stopped moisture and enter in described upper box, guarantee the trouble free service that its inner terminal connects.
(1) the utility model has successfully been avoided a series of security hidden troubles that bring because of terminal box humidity.
(2) the utility model has effectively improved the general level of the health of secondary device, is conducive to protect power equipment, reduces interruption duration, guarantees power supply continuation, increases electricity sales amount, improves Business Economic Benefit.
(3) the utility model has effectively prevented that terminal box is subject to cargo sweat, thereby makes to protect mistaking signal, and the situations such as DC earthing greatly reduce; reduced attendant's workload; the terminal box general level of the health is improved, and has improved operating efficiency, has saved manpower and time cost.
