Switch isolation switch is to use most a kind of electrical equipment in high-voltage switch electric appliance, as the term suggests, it is to play buffer action in circuit
The principles and structure of itself fairly simple, but owing to usage amount is big, functional reliability requires height, to electric substation,
The impact of the design of power plant, foundation and safe operation is the biggest.Disconnecting link be mainly characterized by without arc extinguishing ability, can only be not negative
Divide in the case of charged current, close circuit.High voltage isolator, by the difference of its mounting means, can be divided into outdoor high-voltage isolating switch
With indoor high-voltage isolating switch.Outdoor high-voltage isolating switch refers to bear the effects such as wind, rain, snow, filth, condensation, ice and depth hoar,
It is adapted to mount to the high voltage isolator that balcony uses.
In actual use, foreign body in air or birds can fall out of doors on high-voltage switch blade, careless slightly
May result in the short circuit between wiring bronze medal, Electrical Safety is brought hidden danger.
Additionally at annual summer peak meeting and meet and need to arrange for operation maintenance personnel between the kurtosis teletostage and carry out night infrared thermometric, come
Find disconnecting link heating defect, owing to the observation of temperature can not intuitively be found out, so the workload of operation maintenance personnel is bigger.
Summary of the invention
The purpose of this utility model is: overcome the deficiencies in the prior art, it is provided that the isolation cover of a kind of high-voltage switch blade,
By the effect of isolation cover, it is to avoid bronze medal is exposed in atmosphere, prevent the foreign body in air or birds from falling connecing at switchblade knife
Short circuit is caused on line bronze medal；The bottom of housing is provided with through wires hole, it is ensured that electric wire can be connected with wiring bronze medal；Pass through through wires hole
It is provided with flange, and flange sets up, such that it is able to avoid rainwater to enter in housing；The binding post of wiring bronze medal is positioned at threading
In the range of hole, easily facilitate the wiring of electric wire and wiring bronze medal；Housing is transparent color, and by temperature sensing color changing coating
Effect, can be so that staff observes the temperature of wiring bronze medal position intuitively.
Technical solution adopted in the utility model is:
The isolation cover of a kind of high-voltage switch blade, including high-voltage switch blade, the both sides of described high-voltage switch blade are respectively
Being provided with wiring bronze medal, the both sides of described high-voltage switch blade are positioned at the surrounding of wiring bronze medal and are covered with insulation shell, described insulation
The bottom of housing is provided with threading via hole.
The further improvement project of this utility model is that the edge of described threading via hole is provided with flange.
This utility model further improvement project is that described flange sets up.
This utility model further improvement project is, the binding post of described wiring bronze medal is positioned at the scope of threading via hole
In.
This utility model further improvement project is that described insulation shell is transparent, and the inwall of insulation shell is provided with
Temperature sensing color changing coating.
This utility model further improvement project is, when the temperature in insulation shell greater than or equal to 50 degrees Celsius time
Waiting, temperature sensing color changing coating is red；When the temperature in insulation shell is less than 50 degrees Celsius when, temperature sensing color changing coating is
Bright.
This utility model further improvement project is, when the temperature in insulation shell greater than or equal to 70 degrees Celsius time
