Irreplaceable effect, but high-voltage vacuum load switch finds in actual use, when high-voltage vacuum load switch is running
Time, owing to the moisture content in indoor air environment is of a relatively high, on high-voltage vacuum load switch surface, therefore easily form knot
Dew phenomenon, and when having dewdrop on high-voltage vacuum load switch surface, easily cause high-voltage vacuum load switch to be short-circuited
Fault, the operation safety of serious threat electric power system, and for this problem, be currently mostly by opening at high pressure vacuum load
Outside, pass is set up heating and dehumidification equipment and is controlled, but actual effect is unsatisfactory and needs to expend the substantial amounts of energy.Therefore pin
To this phenomenon, in the urgent need to developing a kind of novel indoor high-voltage vacuum on-load switch structure, to meet actually used need
Want.
Utility model content
For not enough present on prior art, this utility model provides a kind of indoor high-voltage vacuum on-load switch.This is real
Simple with new structure, compact in design, while meeting normal circuit operation manipulation operation, on the one hand effectively improve high pressure
The installation positioning performance of vacuum load switch, on the other hand improves the barrier propterty of high-voltage vacuum load switch, enhances height
Pressure vacuum load switch, to easily occurring the defensive ability/resistance ability of dew condensation phenomenon in environment, reduces conventional high-tension vacuum load switch because of table
Face condenses and power failure occurs, thus improves operation stability and the reliability of high-voltage vacuum load switch.
To achieve these goals, this utility model is to realize by the following technical solutions:
A kind of indoor high-voltage vacuum on-load switch, including disconnecting switch, on-load switch, earthed switch, positioning framework and behaviour
Control axle.Positioning framework is cube frame structure.Disconnecting switch, on-load switch and earthed switch are installed on positioning framework also
In being embedded in positioning framework and it is connected with each other by operating shaft between disconnecting switch, on-load switch and earthed switch.Operating shaft respectively with
Disconnecting switch, on-load switch, earthed switch are hinged.Operating shaft is separately hinged with positioning framework by ratchet mechanism.Posting
Frame rear surface sets rigid insulation ceramic block and connects guide rail.Connect guide rail at least one and by rigid insulation ceramic block and location
Framework connects.Positioning framework side surface and front surface are all provided with transparent insulation protective plate.Transparent insulation protective plate passes through ratchet mechanism
Hinged with positioning framework and be coated on outside disconnecting switch, on-load switch, earthed switch and operating shaft.On transparent insulation protective plate
If at least one open-work.Operating shaft at least one end is positioned at outside transparent insulation protective plate by open-work.
Further, described rigid insulation ceramic block is hinged with positioning framework by ratchet mechanism.
Further, described transparent insulation protective plate inner surface sets silica gel heating bar.
This utility model simple in construction, compact in design, while meeting normal circuit operation manipulation operation, on the one hand have
The installation positioning performance improving high-voltage vacuum load switch of effect, on the other hand improves the protective of high-voltage vacuum load switch
Can, enhance high-voltage vacuum load switch to environment easily occurs the defensive ability/resistance ability of dew condensation phenomenon, reduce conventional high-tension vacuum
