Abstract
The utility model discloses a protective device of a high-voltage electroscope. The protective device comprises a protective cover, a bottom cover and an anti-skid position dividing ring; one end of the protective cover is provided with an internal thread, and the other end of the protective cover is provided with an external thread; the inner wall of the protective cover is provided with a battery box on which a box cover is arranged; the middle of the bottom cover is provided with a hole; and the bottom cover is in threaded connection with the protective cover. The protective device has the advantages that the protective cover, the bottom cover and the electroscope are convenient to disassemble and assemble, a metal connecting screw is prevented from being damaged, the service life of the electroscope is prolonged, the cost is reduced, and the resource waste is reduced; the random rolling phenomenon caused when the electroscope is placed is thoroughly eliminated, and the electroscope is prevented from being damaged; and the aim for rapidly replacing batteries is achieved through arranging a standby battery box.
Description
[technical field] the utility model relates to electric power safety checkout equipment parts, is a kind of protective device of high voltage electroscope specifically.
[background technology] high voltage electroscope is a kind ofly whether to have the mancarried device of operating voltage for detection of electrical equipment, have electrical verification highly sensitive, be not subjected to the advantages such as highfield interference, range of application is very extensive.But in real work, the serviceable life of high voltage electroscope is not long, and spoilage is higher, change very frequent, its main cause is: one, the metal of high voltage electroscope test side is connected screw does not have protective device, exposedly is collided outside, when vibrating, very easily loosening or fracture; Two, the retaining ring of high voltage electroscope handshake terminal is circular design, and electroscope very easily rolls, breaks during placement, the forfeiture checking function; Three, the battery consumption of high voltage electroscope inside is very fast, changes untimely or reserve battery is out of trim, so that the electroscope measuring ability lost efficacy; The electroscope that lost efficacy can not be finished normal testing, also can consist of potential safety hazard to equipment and the person.
[summary of the invention] the utility model provides a kind of protective device of high voltage electroscope for the problems referred to above.
The protective device of this high voltage electroscope comprises protective cover, bottom and anti-skidding minute position ring, it is characterized in that an end of protective cover is provided with internal thread, and the other end of protective cover is provided with external thread; The protective cover inwall is provided with battery case, and battery case is provided with lid; The bottom middle part is provided with the hole, is threaded connection between bottom and the protective cover.
The inside of described anti-skidding minute position ring is circular, and the outside is polygon, and described polygon is 3-8 limit shape.
Anti-skidding minute position ring is fixedly mounted on the boundary of high voltage electroscope handle and insulation division, during work, protective cover under driving is installed on the handle of high voltage electroscope afterbody, and bottom is installed in the test side of high voltage electroscope, and metal is connected screw and stretches out from the hole of bottom; It is complete to work, and drives lower bottom cover, and protective cover is installed in the test side after high voltage electroscope afterbody handle is driven down, and bottom and protective cover are threaded connection; The battery case of the protective cover inwall setting battery that can store for future use.
Advantage of the present utility model: 1, demolition, installation are convenient between protective cover, bottom and the electroscope, effectively avoided metal to be connected the damage of screw, prolong galvanoscopic serviceable life, saved cost, reduced the wasting of resources.Random rolling phenomenon when 2, thoroughly eliminating the electroscope placement has been avoided galvanoscopic damage.3, by stand-by battery box is set, thoroughly solved the problem of quick-replaceable battery.
