Abstract
The utility model discloses metal armoring shifting high-voltage switch equipment comprising a handcart room (3) and a cable room (6). The utility model is characterized in that electric heaters (5,8 ) are respectively arranged in the handcart room (3) and the cable room (6), and the electric heater (5,6) are connected with sensing probes (4,7). By using the above technical scheme, various accidents such as creepage, flashover and the like of various electric power equipment caused by wetting and condensation can be effectively prevented.
Description
Technical field
The utility model relates to a kind of metal-clad moveable formula high voltage switchgear.
Background technology
The inner condensation that takes place of switchgear causes creepage, flashover fault, generally occurs in following several situation:
1, regional humidity height, climate temperature changes greatly, and switch cubicle bottom is moist, the cable trough that has even ponding is arranged;
2, the switch cubicle that has is at basement, and humidity ratio is higher, and the particularly subaerial temperature of temperature is lower than ambient temperature in the cabinet;
3, the equipment that has is in temporary transient shut down condition, and the subenvironment temperature is just low than ambient temperature in the electric cabinet, just very easily forms condensation on its surface, and in this case, in case send electricity to put into operation, accident just may take place thereupon.
In the electric power system at present, increasing novel high-pressure switch cubicle is employed, and its inner space is very compact, for guaranteeing that the reliably working of assurance device is to the protection against the tide in the cabinet, anti-condensation having higher requirement in high humidity area built-in electrical insulation level.
The utility model content
Problem to be solved in the utility model provides a kind of metal-clad moveable formula high voltage switchgear, its objective is the moisture proof, the anti-condensation performance that improve switch cubicle.
To achieve these goals, the technical scheme taked of the utility model is:
This metal-clad moveable formula high voltage switchgear provided by the utility model comprises handcart chamber and cable vault, is separately installed with electric heater in described handcart chamber and inside, cable vault, and described electric heater is connected with sensing probe.
Described electric heater is fixed together by bolt and cabinet.
Described sensing probe is connected with condensation temperature and humidity controller or state indicator.
Described electric heater is aluminium alloy formula, silicon rubber formula or air regulator formula electric heater.
Adopt technique scheme, can prevent various power equipments effectively because make moist, accidents such as that condensation causes is various creepage, flashover also can realize the power equipment protection against the tide, anti-condensation and add the automation of thermal control.
Description of drawings
Below expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure are made brief description:
Fig. 1 is a structural representation of the present utility model;
Be labeled as among the figure:
1, condensation temperature and humidity controller, 2, the state indicator, 3, the handcart chamber, 4, sensing probe, 5, electric heater, 6, the cable vault, 7, sensing probe, 8, electric heater.
Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and operation principle, the manufacturing process of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, prevent effectively various power equipments owing to make moist, accident such as that condensation causes is various creepage, flashover, the technical scheme that the utility model is taked is:
As shown in Figure 1, this metal-clad moveable formula switchgear provided by the utility model, comprise handcart chamber 3 and cable vault 6, be separately installed with electric heater 5 and electric heater 8 in described handcart chamber 3 and 6 inside, cable vault, described electric heater 5 is connected with sensing probe 7 with sensing probe 4 respectively with electric heater 8.
Adopt technique scheme, can prevent effectively various power equipments owing to make moist, accidents such as that condensation causes is various creepage, flashover.
Described electric heater 5 and electric heater 8 are fixed together by bolt and cabinet respectively.
Adopt said structure, can prevent effectively that described electric heater 5 and electric heater 8 from coming off.
Described sensing probe 4 is connected with condensation temperature and humidity controller 1 or state indicator 2 with sensing probe 7.
Adopt said structure, can realize power equipment protection against the tide, anti-condensation and add the automation of thermal control.
Described electric heater 5 and electric heater 8 are aluminium alloy formula, silicon rubber formula or air regulator formula electric heater.
Wherein the electric heater of aluminium alloy formula can be adopted as DJR series, the electric heater of this model has that volume is little, safe, good looking appearance, efficiency of heating surface height, heats is good, moistureproof, anti-condensation and the characteristics of low-temperature heat superior performance, can prevent effectively various power equipments owing to make moist, accident such as that condensation causes is various creepage, flashover.The high-quality heating resistor that heater is selected for use is compared with the heating wire that general heater uses, and improve useful life greatly, can work stably in a long term, and not have naked light, and fail safe is higher.
The electric heater of this model is when work, and its surface temperature is 120 ℃～130 ℃.By air heat radiation dehumidifying, according to manually or automatically input, the excision of control heater of operational environment state, reach moisture proof, anti-condensation function by the user.
The technical scheme that the utility model adopted compared with prior art, has tangible difference, possessed outstanding substantial characteristics, and obtained marked improvement technically, be worth in industrial promotion and application, so, the utlity model has novelty, creativeness and practicality.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection range of the present utility model.
