Abstract
The utility model provides a pincer-like live-line tester for a leakage current of a zinc oxide arrester. A normal digital pincerlike gauge for measuring the leakage current is used, the resolution of the measurement gauge should not be greater than 10 microampere, and a storage function of a measurement peak value should be provided, a jaw is machined to be a circle with a diameter of no less than 8cm, a jaw opening control knob is machined to be a rectangular with a length of about 2cm, at the other side, which is in a backward direction to the jaw, of the measurement gauge, an insulation operating bar with a proper length is fixed, at a proper position at the lower end of the insulation operating bar, a control handgrip is fixed, and an insulation rope is used to connect the control handgrip and the jaw opening control knob.
Description
Affiliated technical field
The utility model relates to electric testing instrument technical field, especially a kind of pincerlike Leakage Current of Zinc-oxide Lightning Arresters testing instrument for electrified.
Background technology
At present, Leakage Current of Zinc-oxide Lightning Arresters has two kinds of method of testings, and the one, have a power failure and test, the 2nd, monitor online.But in real work, a lot of lightning arresters are not installed on-Line Monitor Device, thereby can not grasp in time lightning arrester running status, only have while by the time periodically having a power failure test and just can know.Have a power failure and test Leakage Current of Zinc-oxide Lightning Arresters, both to staff, brought larger workload, to power supply reliability, bring impact again.
Utility model content
In order not need to have a power failure just energy Measurement accuracy Leakage Current of Zinc-oxide Lightning Arresters, the utility model provides a kind of pincerlike Leakage Current of Zinc-oxide Lightning Arresters testing instrument for electrified, as adopt this kind of tester, when Zinc-Oxide Arrester charging operation, just can measure easily and fast Leakage Current of Zinc-oxide Lightning Arresters, time saving and energy saving, simple and easy to do.
The utility model solves the technical scheme that its technical matters adopts: utilize a conventional numeric type to measure the pincerlike meter of leakage current, the resolution of meter meter should be not more than 10 microamperes, and should there is the peak value of measurement hold function, jaw, meter meter, insulating bar is sequentially connected, its jaw is processed into the circle that diameter is not less than 8cm, the processing of jaw opening and closing control knob is into about the long rectangle of 2cm, meter meter the opposing party of jaw dorsad, fix a suitable length insulating bar, at the lower end of insulating bar correct position, fix a control handgrip, with an insulating cord, control handgrip and jaw opening and closing control knob are coupled together.
While measuring Leakage Current of Zinc-oxide Lightning Arresters, hold control handgrip, insulating cord pulls downwards, and jaw opening and closing control knob is pulled downwards, and jaw opens, with jaw, block appropriate location, Zinc-Oxide Arrester device body bottom, unclamp control handgrip, can measure, meter meter will be measured peak value and preserve, take off the utility model, can carry out reading.
The beneficial effects of the utility model are, when Zinc-Oxide Arrester charging operation, just can measure easily and fast Leakage Current of Zinc-oxide Lightning Arresters, time saving and energy saving, simple and easy to do.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural drawing of the present utility model.
1. meter meters in Fig. 1,2. jaw, 3. insulating bar, 4. jaw opening and closing control knob, 5. insulating cord, 6. control handgrip.
Embodiment
In Fig. 1, utilize a conventional numeric type to measure the pincerlike meter of leakage current, the resolution of meter meter (1) should be not more than 10 microamperes, and should there is the peak value of measurement hold function, its jaw (2) is processed into the circle that diameter is not less than 8cm, jaw opening and closing control knob (4) processing is into about the long rectangle of 2cm, meter meter (1) the opposing party of jaw (2) dorsad, fix a suitable length insulating bar (3), lower end correct position at insulating bar (3), fix a control handgrip (6), with an insulating cord (5), jaw opening and closing control knob (4) and control handgrip (6) are coupled together.
While measuring Leakage Current of Zinc-oxide Lightning Arresters, hold and control handgrip (6), insulating cord (5) pulls downwards, and jaw opening and closing are controlled (4) button and pulled downwards, and jaw (2) opens, with jaw (2), block appropriate location, Zinc-Oxide Arrester device body bottom, unclamp and control handgrip (6), can measure, meter meter (1) will be measured peak value and preserve, take off the utility model, can carry out reading.
Claims (2)
1. a pincerlike Leakage Current of Zinc-oxide Lightning Arresters testing instrument for electrified, jaw, meter meter, insulating bar are sequentially connected, it is characterized in that, in the lower end of insulating bar, there is a control handgrip, with an insulating cord, control handgrip and jaw opening and closing control knob are coupled together.
2. a kind of pincerlike Leakage Current of Zinc-oxide Lightning Arresters testing instrument for electrified according to claim 1, is processed into by its jaw the circle that diameter is not less than 8cm, and jaw opening and closing control knob is processed into the long rectangle of 2cm.
