Description
Technical field
The utility model relates to a kind of electric power facility testing tool, especially relates to a kind of high voltage testing device.
Background technology
Along with the Fast Construction of extra high voltage network with put into operation, power circuit and equipment have a power failure to detect with hot line job and launch rapidly.Wherein, judge that whether charged circuit, the equipment safety for interruption maintenance operating personnel be most important, the conventional a kind of testing tool of electric system when high voltage testing device, there is following shortcoming in current technology:
1) operating personnel, in the time detecting, can run into not accessible high-tension line, cause electrical verification difficulty.When high voltage testing device uses, operating personnel should wear insulating glove, hold the handshake part below retaining ring, or adopt the mode of insulating bar binding high voltage testing device to carry out eminence electrical verification, guarantee and electrified body keep enough distances like this, ensure operating personnel's life safety, prevent from getting an electric shock, but the inconvenience of use, inefficiency.
2) AC and DC circuit electrical verification is at present used respectively AC and DC electroscope, can not realize mutual use.
Therefore need to develop a kind of easy to operate, reliability strong, be applicable to the high voltage testing device of alternating current-direct current electrical verification.
Chinese patent 201310151526.5 discloses a kind of New type AC, DC high voltage testing device, comprise switch, detection probe, insulated handle, scalable insulation rod, acoustic-optic indicator unit, existence must arrange change-over switch could realize the shortcomings such as alternating current-direct current electrical verification, inconvenient operation.
Summary of the invention
The purpose of this utility model be exactly provide in order to overcome the defect that above-mentioned prior art exists a kind of easy to operate, reliability strong, be applicable to the high voltage testing device of alternating current-direct current electrical verification.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of high voltage testing device, comprise housing, metal cap, electroscope, conducting ring, insulating bar and operating grip, described case top connection metal cap, bottom connects insulating bar, electroscope is equipped with in inside, described insulating bar attended operation handle, described conducting ring is positioned at housing bottom and is enclosed within on insulating bar, and described electroscope is connected with metal cap, conducting ring respectively by wire.
Described insulating bar is telescopic rod.
Described conducting ring is the ring texture of being made up of elasticity or flexible material.
Battery, light-emitting device and hummer are installed on described electroscope.
Described galvanoscopic testing circuit adopts isolated gate FET.
Compared with prior art, the utlity model has following advantage:
1) electroscope in the utility model adopts the isolated gate FET of high impedance to replace in traditional testing circuit " triode+gate circuit ", its input impedance is significantly improved, not only can respond to ac high-voltage, also can respond to DC electrostatic field, the charged display device that substitutes high direct voltage voltage table or line with ground detects whether there is high direct voltage, and sensitivity is corresponding raising also.
2) conducting ring that the utility model forms by resilient material is set, is not only conveniently used for Authentication devices and whether has high direct voltage, and can contact with the equipment of variety classes size easily, uses very convenient.Only need to be by an exit of metal cap 9 contact electrification equipment when use, conducting ring contacts another exit, in the time there is high direct voltage between two exits, this voltage will be by the electroscope of insulated-gate field-effect, play the effect that detects high direct voltage, be furnished with light-emitting device and hummer for warning simultaneously.
3) insulating bar of the present utility model is telescopic, and the convenient device height detecting as required regulates use.
Brief description of the drawings
Fig. 1 is a kind of structural drawing of high voltage testing device;
In figure: l, housing 2, metal cap 3, electroscope 4, conducting ring 5, insulating bar 6, operating grip 7, battery 8, light-emitting device 9, hummer.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.The present embodiment is implemented as prerequisite taking technical solutions of the utility model, provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure l, a kind of high voltage testing device, comprise housing 1, metal cap 2, electroscope 3, conducting ring 4, insulating bar 5 and operating grip 6, housing l top connection metal cap 2, bottom connects insulating bar 5, and electroscope 3 is equipped with in inside, insulating bar 5 attended operation handles 6, conducting ring 5 is positioned at housing l bottom and is enclosed within on insulating bar 5, and electroscope 3 is connected with metal cap 2, conducting ring 4 respectively by wire.Insulating bar 5 is telescopic.Conducting ring 4 is made up of the elasticity such as conductive rubber, metal net or flexible material.Battery 7, light-emitting device 8 and hummer 9 are installed on electroscope 3.
The testing circuit of electroscope 3 adopts isolated gate FET, replace the testing circuit of traditional " triode+gate circuit ", its input impedance is significantly improved, therefore sensitivity significantly improve, as long as probe approaches electricity, row just can start immediately, also can directly respond to or respond to by responding to its high-frequency harmonic component carrying for the larger DC high voltage electric field of amplitude, except the extremely low region of only a few electric potential difference, can start immediately alarm, overcome traditional electroscope low-response, sensitivity is low, there is the shortcoming of operating dead zone, also solve high direct voltage and checked difficult present situation.
When the utility model uses, put on hand insulating glove, then hold operating grip 6, regulate the length of insulating bar 5, by an exit of metal cap 9 contact electrification equipment,, in conducting ring 4 another exits of contact in the time there is high pressure between two exits, this voltage will pass through electroscope 3, judges whether to exist high pressure by light-emitting device 8 and hummer 9.
The conducting ring 4 that the utility model forms by resilient material is set, can be conveniently used for Authentication devices and whether have high direct voltage, the AC current detector that solves prior art cannot be verified DC voltage, exist electrical verification to have the shortcoming of function blind area, for example: the minority power equipments such as power cable, power capacitor are after having a power failure completely, even if there is not induced voltage, the high direct voltage that also can exist residual charge to cause; And this conducting ring 4 is for elasticity or flexible material can be out of shape, and can contact with the equipment of variety classes size easily, uses very convenient.
