Abstract

The utility model discloses a safety equipment voltage withstand test special device which comprises two rod insulators and a telescopic mechanism. One end of each of the two rod insulators is hinged and connected through a rotating shaft. Two ends of the rotating shaft are provided with a shell with a hook. The two rod insulators are hinged and connected with the telescopic mechanism. An electrical telescopic rod is arranged between the two rod insulators. The telescopic mechanism is provided with a plurality of device connecting mechanisms. The electrical telescopic rod is arranged between the two rod insulators, and when an insulation rod is lifted, the insulation performance of the rod insulators is not reduced. At the same time, a special high high-rise building distance test house is not needed and a long insulation rod can be detected. When the long insulation rod is measured, one end of the insulation rod can be provided with an insulation supporting piece, thus the insulation rod is tilted in the air, and the detection of the long insulation rod is facilitated. Sliding clamps are connected with a current alarm and fuses, when equipment is failed, the damage of a detection device is avoided, the maintenance personnel are notified timely, and the economic losses are avoided.

Technical field
The present invention relates to electric system instrument leakage current measurement equipment and technology, particularly a kind of managing security tools and instruments withstand voltage test special purpose device.
Background technology
Along with economic development, power supply reliability requires also more and more higher.Personal safety is the basis of power system development, and managing security tools and instruments is the technological means that ensures power worker's personal safety.< electric-power safe instruments preventive trial rules > requires: managing security tools and instruments (electroscope, insulating bar) carries out power frequency withstand test every year one time.Owing to there is no special security tool Withstand test device, the method adopting at present has 2 kinds, 1) managing security tools and instruments (electroscope, insulating bar) upper end is directly fixed on ac test generator top, and lower end is placed directly on the ground.Because upper end fixed position is not firm, there is managing security tools and instruments (electroscope, insulating bar) landing phenomenon at the trial.2) adopt managing security tools and instruments (electroscope, insulating bar) two ends to be fixed on framework, the method for middle pressurization, this method time is longer, if while testing many experimental safe Work tools (electroscope, insulating bar), test length can not meet simultaneously simultaneously.
Existing withstand voltage test equipment, withstand voltage test platform of live line tool as disclosed in CN202330626U, described withstand voltage test platform of live line tool is made up of jacking gear, insulation assembly, high-field electrode support, high-field electrode folder, ground electrode folder, jacking gear is fixed on pilot region overhead, high-field electrode support is connected with jacking gear by insulation assembly, test product upper end is hung vertically on high-field electrode support by high-field electrode folder, and test product lower end is connected with ground wire by ground electrode folder.Its weak point is: 1) because equipment will be lifted on roof, and will use rod insulator to insulate, need to build special high floor interval experiment room, adopt electric block and driving, cost of investment is high, expensive.2) instrument is installed and extremely inconvenience of dismounting, and contact effect is bad.3) do not have and report to the police and protective device, when utensil exists fault, electric current is excessive, causes pick-up unit easily to damage, and causes unnecessary economic loss.4) can not carry out sectionalization test, the insulating bar insulating property that detect are inaccurate.
Utility model content
The utility model, for prior art above shortcomings, provides a kind of managing security tools and instruments withstand voltage test special purpose device, adopts after this device, cost of investment is low, can save a large amount of time, can guarantee that again short circuit is firm, also can carry out sectionalization test, and easy accessibility is quick.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of managing security tools and instruments withstand voltage test special purpose device, comprise two rod insulators and telescoping mechanism, two rod insulator one end are articulated and connected by rotating shaft, rotating shaft two ends arrange the housing with hook, two rod insulators and telescoping mechanism are articulated and connected, and between two rod insulators, electric expansion bar are set, and several utensil bindiny mechanisms are set on described telescoping mechanism.
Described telescoping mechanism comprises connecting link and is arranged on the expansion link at connecting link two ends.
Described utensil bindiny mechanism comprises the screw being arranged on telescoping mechanism and the bolt matching with screw, and one end of this bolt arranges utensil chuck.
Described connecting link two ends are connected by bearing with expansion link.
Said apparatus also comprises the sliding clamp being sleeved on insulating bar.
Described sliding clamp is connected with current alarm and fusible link.
Managing security tools and instruments withstand voltage test special purpose device of the present utility model, by electric expansion bar is set between two rod insulators, in the time slinging insulating bar, can not reduce the insulating property of rod insulator, do not need special high floor interval experiment room, just can detect long insulating bar simultaneously; In the time measuring long insulating bar, insulating bar one end can arrange insulated support, and insulating bar is tilted in the air, is convenient to detect long insulating bar; Described connecting link two ends are connected by bearing with expansion link, in the time of installation or removal insulating bar, control electric expansion bar and shrink, and connecting link can rotate, and screw is horizontal, and are convenient to install and dismounting insulating bar; Said apparatus also comprises the sliding clamp being sleeved on insulating bar, and sliding clamp can be fixed in any position of insulating bar, conveniently carries out sectionalization test; Described utensil bindiny mechanism comprises the screw being arranged on telescoping mechanism and the bolt matching with screw, and one end of this bolt arranges utensil chuck, be threaded, contact firmly, convenient connection.Described sliding clamp is connected with current alarm and fusible link, when utensil exists fault, avoids pick-up unit to damage, and while maintainer, avoids causing economic loss in time.
