Description
Technical field
The utility model relates to high-tension circuit checkout equipment technical field, is specially a kind of lengthening formula working metal contact electroscope.
Background technology
Electroscope is the special purpose device whether detection electrical equipment or circuit exist operating voltage, and distribution network systems generally adopts 10KV distribution feeder pillar and ring main unit in existing electric system, in 10KV distribution feeder pillar and ring main unit, some load transition head outsides are insulators, the nonisulated body that only has electroscope to touch the inside just can carry out electrical verification operation, and existing electroscope contact is generally shorter, effective contact electrification body, and electrical cables elbow head to be tested or T headband electricity position are shorter, for electrical verification work brings many troubles, and increased unsafe factor for work.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of lengthening formula working metal contact electroscope.
For solving above-mentioned technical matters, the utility model is by the following technical solutions: a kind of lengthening formula working metal contact electroscope, comprise electroscopy equipment and steady arm, steady arm one end connects holding rod by isolation retaining ring, and the other end connects electroscopy equipment by telescopic insulating device; Telescopic insulating device comprises insulating bar, and insulating bar one end connects electroscopy equipment, the outside socket of other end first set cylinder; The first sleeve outer cover connects the second sleeve, and one end of the second sleeve electroscopy equipment far away connects steady arm; Between insulating bar and the first sleeve, be provided with articulating device, articulating device comprises the ball that is connected to insulating bar surface by stage clip, and be arranged on the first sleeve lining for the fixing groove of ball screens; Between the first sleeve and the second sleeve, be also provided with articulating device, its ball is connected on first set drum outer wall by stage clip, and the groove coordinating with this ball is arranged on the inwall of the second sleeve; When telescopic insulating device is stretched to when the longest, the ball of articulating device falls into corresponding groove.
Further, between isolation retaining ring and holding rod, be also connected with holding rod lengthening section.
Further, holding rod is also enclosed with rubber sleeve away from one end of isolation retaining ring.
Compared with prior art, the beneficial effects of the utility model are: the utility model can be according to actual electrical verification process need, the galvanoscopic length of telescopic adjustment, and can further regulate galvanoscopic length by increasing holding rod lengthening section, reduced cable elbow head too short or treat the too high inconvenience bringing to electrical verification work of electroscopy equipment.The utility model is simple in structure, and convenient operation has improved security, reliability, accuracy and the agility of electrical verification personnel operations.

Embodiment
By reference to the accompanying drawings, a kind of lengthening formula working metal contact electroscope, comprises electroscopy equipment 1 and steady arm 6, and steady arm 6 one end connect holding rod 8 by isolation retaining ring 7; It is characterized in that, steady arm 6 other ends connect electroscopy equipment 1 by telescopic insulating device; Telescopic insulating device comprises insulating bar 2, and insulating bar 2 one end connect electroscopy equipment 1, the outside socket of other end first set cylinder 3; First sleeve 3 outside socket the second sleeve 4, the second sleeves 4 connect steady arm 6 away from one end of electroscopy equipment 1; Between insulating bar 2 and the first sleeve 3, be provided with articulating device 5, articulating device 5 comprises the ball 5b that is connected to insulating bar 2 surfaces by stage clip 5a, and be arranged on the first sleeve 3 inwalls for the fixing groove 5c of ball 5b screens; Between the first sleeve 3 and the second sleeve 4, be also provided with articulating device 5, its ball 5b is connected on the first sleeve 3 outer walls by stage clip 5a, and the groove 5c coordinating with this ball 5b is arranged on the inwall of the second sleeve 4; When telescopic insulating device is stretched to when the longest, the ball 5b of articulating device 5 falls into corresponding groove 5c.
Wherein electroscopy equipment 1 comprises that skin is coated with the series resistor of insulation course, series resistor one end connection metal working contact, and the other end connects display lamp and alarm by lower lead-in wire simultaneously.When using electroscope to detect electrical verification, working metal contact is to position to be detected, when there is voltage at position to be detected, electric current passes through from series resistor, alarm sends the alarm sound of buzzing, display lamp sends the light of discontinuity flicker simultaneously, and staff is pointed out, and testing finishes.
When the position to be detected of cable is shorter or device location to be detected is higher, for more convenient, carry out electrical verification work, can be by regulating telescopic insulating device regulate galvanoscopic length.
For further lengthening galvanoscopic length, between isolation retaining ring 7 and holding rod 8, be also connected with holding rod lengthening section 9.Between isolation retaining ring 7, holding rod lengthening section 9 and holding rod 8, adopt and be threaded.Can select as required whether to increase holding rod lengthening section 9.
For making more convenient operation, holding rod 8 has also been enclosed with the rubber sleeve 10 of anti-skidding effect away from one end of isolation retaining ring.
