Abstract
The utility model discloses a moist resistant and condensation resistant apparatus for a high tension switchgear, comprising electric heaters installed in a handcart chamber and a cable chamber of the high tension switchgear. The moist resistant and condensation resistant apparatus can effectively prevent various electric devices from various accidents such as creepage and flashover initiated by damp and condensation and realizes condensation automatic control.
Description
Technical field
The utility model relates to a kind of high voltage switchgear, relates in particular to a kind of moisture proof of high voltage switchgear, anti-condensation device.
Background technology
If high voltage switchgear inside humidity is excessive or the condensation phenomenon takes place, cause creepage, the inner flashover fault with fixed attention that takes place easily, cause serious consequence.The reason that produces generally is divided into following several kinds: 1, regional humidity is high, and climate temperature changes greatly, humidity bottom the switchgear, the cable trough that has even ponding is arranged; 2, the switchgear that has is at basement, and humidity ratio is higher, and the particularly subaerial temperature of temperature is lower than ambient temperature in the equipment; 3, the switchgear that has is in temporary transient shut down condition, and the subenvironment temperature is just low than ambient temperature in the equipment, just very easily forms condensation on its surface.In these cases, in case send electricity to put into operation, accident just takes place thereupon.
In the electric power system at present, increasing novel high-pressure switchgear is employed, and its inner space is very compact, and for guaranteeing the built-in electrical insulation level in the high humidity area, the assurance device reliably working is had higher requirement to moistureproof, anti-condensation in the equipment.
The utility model content
The purpose of the utility model provides a kind of moisture proof of high voltage switchgear, anti-condensation device, has solved the problem of the excessive and condensation of the inner incidental humidity of existing high voltage switchgear.
For realizing above-mentioned purpose, adopt following technical scheme:
A kind of moisture proof of high voltage switchgear, anti-condensation device, said moisture proof, anti-condensation device comprise electric heater, said electric heater is installed on the handcart chamber and the cable vault of high voltage switchgear.
As a preferred version; Said electric heater links to each other with condensation temperature controller or state indicator; Condensation temperature controller or state indicator link to each other with sensing probe; Said sensing probe is installed in handcart chamber and the cable vault, and condensation temperature controller or state indicator are installed on the high voltage switchgear panel.
As further preferred version, said electric heater is a DJR series alloys electric heater.
The utility model is through electric heater control high voltage switchgear interior humidity; The DJR series alloys electric heater that is adopted has that volume is little, safe, good looking appearance, the efficiency of heating surface is high, heats is good characteristics, can prevent effectively various power equipments owing to make moist, accidents such as that condensation causes is various creepage, flashover.And, realized moistureproof, the anti-condensation of power equipment and added the automation of thermal control through sensing probe and corresponding control appliance are installed.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below:
Fig. 1 is the high voltage switchgear front schematic view of the utility model after installing;
Fig. 2 is the high voltage switchgear internal structure sketch map of the utility model after installing.
Among the figure:
1, condensation temperature and humidity controller; 2, sensing probe one; 3, electric heater one; 4, sensing probe two; 5, electric heater two.
Embodiment
Below in conjunction with accompanying drawing, further specify the utility model through embodiment.
Shown in Fig. 1-2; Be an embodiment of the utility model, a kind of moisture proof of high voltage switchgear, anti-condensation device comprise electric heater 3,5, condensation temperature controller 1 and sensing probe 2,4; Said electric heater 3,5 and sensing probe 2,4 are installed on the handcart chamber and the cable vault of high voltage switchgear; Electric heater 3,5 links to each other with condensation temperature controller 1, and condensation temperature controller 1 links to each other with sensing probe 2,4, and condensation temperature controller 1 is installed on the high voltage switchgear panel.
As shown in Figure 1, be the high voltage switchgear front schematic view after the utility model installation, condensation temperature controller 1 is installed on the high voltage switchgear panel, can set the upper and lower limit parameter value of device interior temperature, humidity.
As shown in Figure 2, sensing probe 1, sensing probe 24 detects handcart chambers and cable indoor temperature, humidity, and gives condensation temperature controller 1 with transfer of data.When air humidity reached set point in the equipment, condensation temperature controller 1 promptly sent signal, drive by computer starting electric heater 1 and electric heater 25 wet, to destroy the condition that produces condensation in the air.When temperature reached set point in the equipment, condensation temperature controller 1 was promptly controlled electric heater 1 and is stopped heating with electric heater 25.
The utility model can prevent effectively various power equipments owing to make moist, accidents such as that condensation causes is various creepage, flashover, and the automation control that has realized putting condensation.
