Description
Technical field
The present invention relates to power maintenance tool field, particularly, the present invention relates to a kind of high-voltage alternating electrical verification rod, described high-voltage alternating electrical verification rod system uses the principle of umbrella handle to improve the problem that used electrical verification rod falls back.Electrical verification bar structure of the present invention is simple, easy to use and reliable, adds security during electrical verification simultaneously.
Background technology
Along with the development of power industry, electrical network, power regulation station are more and more, need regularly to use electrical verification rod in a large number in the maintenance of various circuit, power regulation station etc., the convenience how realizing the operation of electrical verification rod is run into the required problem solved in operation with safety.
High voltage electroscope is also called high pressure electricity measurer, is a kind of for detecting the mancarried device that on electrical equipment, whether operating voltage exists.There is the features such as easy to carry, electrical verification is highly sensitive, be not subject to highfield interference, possess whole circuit self-checking function, stand-by time is long.Main Types sound light type electroscope (bar-shaped telescopic clectroscope, condensing type electroscope, GDY/GD/GSY type electroscope), language type electroscope, windmill type electroscope, rain proof type electroscope etc.
Principle of work: electro transfer, the electrons on energized conductor is transferred on electroscope.Remove energized conductor, electroscope metal forming continues to open
The structure of electrical verification rod that we commonly use now is divided into two parts: the electrical verification rod at top, electrical verification handle, electrical verification handle is generally formed by connecting by more piece handle, described electrical verification rod is scalable, during use, pull-out is by more piece handle, form longer electrical verification rod length, so that use electrical verification rod in all cases.When not using, then receive short pulled out more piece handle, so that collection.
In pull-out by more piece handle, when forming longer electrical verification rod length use, described electrical verification rod saves by each the handle friction force each other pulled out to fix its length.But it is evident that, service time one is long, and the handle pulled out friction force is each other often inadequate.Now, often there will be that to hold the electrical verification rod time high longer and cause electrical verification rod situation about falling because of operating personnel; Or, occur, because described electrical verification rod makes in purposes, accidentally to encounter the hamper of equipment etc., the situation that the handle friction force each other causing electrical verification rod to pull out equally falls not.Like this, just often cause operation maintenance personnel can not carry out electrical verification fully, or the possibility having safe distance inadequate.
Portable stretchable type electrical verification rod utilizes new insulation material to process. it has elongation, shrinkable feature again. become and take the formula novel electrical verification rod that stretches and be convenient to use in the every high-voltage test in outdoor, the essential weapon of personal safety ensureing each testing crew. change is taken formula concertina type electrical verification rod and is easy to carry, convenient, flexible, have that volume is little, weight is clear, safe and reliable, be the indispensable security tools of high voltage operation personnel.
Summary of the invention
For solving the problem, the present invention is directed to the problem existing for service condition and the shortcoming of common electrical verification rod, original electrical verification bat handle design being improved, the object of the invention is to:

Embodiment
Below, according to specification drawings and specific embodiments, a kind of umbrella handle formula high-voltage alternating electrical verification rod of the present invention is further described in detail.
Embodiment 1
A umbrella handle formula high-voltage alternating electrical verification rod, applicable electric pressure: 110KV returns state length 60cm and stretches state length 200cm.
Described umbrella handle formula high-voltage alternating electrical verification rod effectively insulated lengths: 1900mm decreased food: 80mm joint number: 3, retaining ring diameter: 57mm contacts electrode length: 40mm.
Described umbrella handle formula high-voltage alternating electrical verification bar structure is divided into two parts: the electrical verification rod at top, electrical verification handle, main transformation part is electrical verification handle.A duck eye at the mode of fixing umbrella mainly a built-in spring steel ball and each joint top of umbrella handle.
In the present embodiment, circular arc steel ball: the steel ball of an embedded arcuate surface, band spring on the outer wall that each saves (except final section) bottom handle, expose steel ball part about 1/3rd, be fixed at handle inner with spring, make it have elastic force.
Through hole: dig a through hole at each joint handle top (except first segment) outer wall, when through hole runs into steel ball when stretched steel ball can ejecting card in through-holes, two joint handles are fixed.Utilize the circular arc surface of contact of steel ball and the elasticity of steel ball, make second section handle exert oneself one to push away namely recoverable, the steel ball of first segment handle need be pressed with hand and regain.
Groove: each joint handle outer wall needs making groove, makes each joint handle can not rotate when flexible, ensures that steel ball and handle are all the time on the same tangent plane of handle.
Groove bayonet socket: in order to ensure that handle is in drawing process, steel ball snaps into after in through hole and can not continue to be drawn out, and after completing pulling action, the groove between two joint handles needs making bayonet socket, allows its length fix.
Embodiment 2
In the present embodiment, except following difference, other are as embodiment 1, obtain electrical verification of the present invention rod.
The circular arc surface of contact of steel ball can form concavo-convex surface of contact, is formed with the threaded joints of a circumference between the Flexible Connector periphery of handle one end of described scalable socket and the through hole inner circumferential contact site for another handle of receiving or ejecting this Flexible Connector.The described threaded joints being formed at the through hole inner circumferential contact site of another handle is formed at described through hole inner circumferential contact site top.
The Flexible Connector arranged because of the handle connecting portion of described scalable socket and for receive or eject this Flexible Connector through hole contact site between be formed with the threaded joints of a circumference, thus, self-locking is formed behind steel ball card stop-pass hole, be unlikely to occur because described electrical verification rod makes in purposes, accidentally encounter the hamper of equipment etc., or make two joint handles connect the situation about falling that gets loose because the handle friction force each other causing electrical verification rod to pull out by steel ball is inadequate by mistake.When needs retraction handles, then only need pin steel ball and slightly rotate simultaneously, make this steel ball and through hole contact site break away from the state of being spirally connected, the connection of two joint handles can be made to get loose.
Embodiment 3
The Flexible Connector arranged except the handle connecting portion of described scalable socket and for receive or eject this Flexible Connector through hole contact site between form irregular surface of contact respectively, to strengthen friction force, outside the threaded joints formed between replacement Flexible Connector and through hole contact site, other are as embodiment 1, form umbrella handle formula high-voltage alternating electrical verification of the present invention rod.
According to the present invention, the thinking of transformation electrical verification bat handle mainly imitates the stretching structure of umbrella handle, and its low cost, structure are easily understood, easy to use and reliable, add security during electrical verification simultaneously.
