Description
Technical field
The present invention relates to electrical equipment technical field, more particularly to a kind of contact high voltage electroscope.
Background technology
At present, high voltage electroscope is that electric system is used when carrying out inspection operation to high-tension line and its high voltage electric equipment
To examine a kind of whether powered instrument of electrical equipment.With flourishing for China's power industry, managing security tools and instruments is wanted
It is also higher and higher to ask.There are various different principles, different types of high voltage electroscope on the market at present.
At this stage, 500kV and the electrical verification of above transmission line of electricity use common contact-type electroscope more.Operating personnel stands in steel tower
At cross-arm, the insulating cord that head bolt has contact measurement component is put down, connects the metal probe type electrical verification on detection part head
Contact and conductive contact, have silent and flash of light to judge whether conducting wire is powered by warning device.In the process, due to super special
Distant with drainage thread at high-voltage transmission line towers cross-arm, operating personnel is difficult to judge only several centimetres in operation
Whether the contact wire of long electrical verification contact head, this brings very big inconvenience to electrical verification work.It is furthermore possible that operating personnel occurs
Contacted and the situation of actual not contact wire since the collimation error causes to be mistakenly considered electrical verification contact head, this is given after electrical verification
Operation（Such as hang ground wire）Bring very big security risk.
The content of the invention
The present invention is in order to overcome deficiency of the prior art, there is provided one kind can avoid operating personnel due to distance is remote,
The contact high voltage electroscope that probe is small and judges by accident.
To achieve these goals, the present invention uses following technical scheme：
A kind of contact high voltage electroscope, including detection part, insulating element and head is held, hold head and be arranged on the upper of insulating element
End, detection part are arranged on the lower end of insulating element, and detection part includes electrical verification contact head, warning device and electrical verification generator,
Electrical verification contact head is in caged, and warning device and electrical verification generator are wrapped in caged electrical verification contact head.Electrical verification contact head and lead
The way of contact of line becomes contact of the body with line by contact of the line with line, adds contact model of the electrical verification contact head with conducting wire
Enclose, avoid operating personnel due to distance is remote, probe is small and judges by accident security risk.
Preferably, warning device includes buzzer and warning lamp, warning lamp is set up.Traditional electroscope warning lamp court
Side is installed, and since operating personnel's distance of wire is then difficult to judge farther out, the warning lamp installed upward can be by the work of surface
Industry personnel easily identify.By sound-light alarm, dual display, it is ensured that work safety.
Preferably, insulating element is insulation ropes.Traditional insulating element is usually telescopic insulating bar, but
Be due to needs extension type operation pole length it is longer, weight is very heavy, to operation and carry all bring some inconvenience, insulate
Rope light weight, can coil storage, convenient operation and carrying.
Preferably, detection part is connected with insulation ropes by a connector, connector lower end is provided with external screw thread,
Detection part upper end is provided with internal thread, and detection part and connector are threadedly coupled, and connector is equipped with through hole along axis, connects
Head lower end is provided with heavy platform, and insulation ropes is pierced by from through hole, and insulation ropes lower end knots and is fastened in heavy platform.This structure
Insulation ropes and detection part can be smoothly connected, and can easily replace insulation ropes.
Preferably, connector is from through hole periphery, some clamp clips, some clamp clip peripheries are drawn in parallel fixation upwards
Sustained height is provided with card slot, an annular elastic band is arranged with each card slot, the lock of adjusting elasticity is provided with elastic band
Button.Such structure can prevent insulation ropes from deviating from from connector lower end so that connector connects fastening with insulation ropes.
Preferably, electrical verification generator includes pressure-resistant current limliting module, electric current Zoom module, selftest module and multi-harmonic-oscillations mould
Block.Pressure-resistant current limliting module ensures electric current caused by high pressure in sufficiently small scope and ensures its current direction to be connect from electrical verification
Contact flows to the inside of electroscope, and then electric current makes size of current be enlarged into certain multiple and makes electricity through overcurrent Zoom module
Stream can be most by subsequent conditioning circuit, and then electric current passes through multi-harmonic-oscillations module, produces the oscillator signal of certain frequency, is transmitted to
Warning device, makes warning device alarm.The effect of selftest module is that electroscope itself circuit is carried out before high voltage testing operation
Self-test, for judging that can alarm circuit work normally, if the failures such as open circuit occur.
Therefore, the present invention has the advantages that：Using caged electrical verification contact head, electrical verification contact head and conducting wire are added
Contact range, avoid operating personnel due to distance is remote, probe is small and judges by accident security risk.
