Description

Electronic ground wire action bars

Technical field

The utility model belongs to the electrical safety apparatus, relates in particular to a kind of electronic ground wire action bars.

Background technology

When high pressure and ultrahigh voltage power equipment interruption maintenance, must carry out ground connection, often make the property-line action bars.But, in real work, be difficult to avoid sending the generation of the serious accident of electricity and charged hanging ground-wire with ground wire, seriously jeopardize network system safe operation and personal safety.

At present, the multiple earth connection action bars in existing public technology and the use only has type hand or semi-automatic, does not still have power type, automatic type or meet energized conductor to shift to an earlier date alarm type.For a long time, puzzled by three significant problems all the time, the one, manual operation is wasted time and energy; The 2nd, add not tightly at 4 meters and above high vacancy dress hanging ground-wire wire clamp, contact resistance is big, can not bear short-circuit current rush, can't guarantee the life security of high voltage electric power equip ment interruption maintenance; The 3rd, can not directly prevent charged hanging ground-wire accident, can't guarantee operating personnel's life security.

Multiple earth connection action bars in existing public technology and the use, also some can realize the operating function of stepping up of ground wire wire clamp, as double hose ground wire hook stick (patent No. ZL 200720107464.8) etc., owing to be subjected to the restriction of manual control mode, total joint number of action bars can only be a joint, its length can not be oversize, generally all less than 2 meters.Otherwise, not only be not easy to carry, also can't preserve into security tool chamber and insulating tool cabinet.

Alarming in short range of electric power device kind in existing public technology and the use is more, all be the fixed voltage grade, generally be mounted in safety cap, wrist-watch, above the work clothes, mainly be applicable to the overhaul of the equipments workmen, when in the safe range that has a power failure, working, can prevent the mistakenly entering into charged equipment interval.During the person on duty of transformer station personnel operation, can't use above-mentioned alarming in short range of electric power device at the frequent mobile working in the charging equipment zone of various different electric pressures.

The utility model content

Waste time and energy in order to overcome the manual operation of existing ground wire action bars, dress hanging wire clamping connection gets an electric shock resistance greatly in high vacancy, can not directly prevent three major safety problems of charged hanging ground-wire accident, and the utility model provides a kind of electronic ground wire action bars.

The technical scheme that the utility model adopted is:

A kind of electronic ground wire action bars, mainly comprise insulated tube and the insulating bar that is connected with insulated tube, wherein, top at insulating bar, be disposed with that the spring energy-storage bolt-lock is buckled, spring energy-storage bolt take-up device, spring energy-storage bolt take-up device below is provided with electronic pull bar, automatic control equipment and high-energy battery.

On spring energy-storage bolt take-up device, be provided with successively three spring energy-storage bolt-locks buckle and the mole near switch, below electronic pull bar, be provided with electronic pull bar motor.

Electronic pull bar motor is fixed in the insulated tube, below electronic pull bar motor, pack into successively alarming in short range of electric power device, automatic control equipment, relay indicating light, alarming horn, alarm lamp, high-energy battery, insulated tube is provided with the insulating bar joint, and insulated tube is connected on the insulating bar by the insulating bar joint.

The good effect of technical solutions of the utility model is:

The utility model ground wire wire clamp that can pin automatically or thread off, automatically handle wire clamp and step up conductor, when running into energized conductor, can in safe distance, report to the police in advance, and take off wire clamp automatically, realization ground wire wire clamp is operated automatically, can ensure that ground wire wire clamp contact resistance is qualified, can reliably prevent charged hanging ground-wire accident again.

When the ground wire wire clamp inserts ground wire action bars head end, automatic locking residence line wire clamp, tension wire clamp spring, open the wire clamp opening, be convenient to hang up conductor or take off from conductor, after 30 seconds, wire clamp unclamps the wire clamp spring automatically hanging up properly on the conductor or taking off when putting back to ground from conductor, tightens up the wire clamp opening and steps up conductor or reset, wire clamp and ground wire action bars head end are threaded off automatically, solve the automatic manipulation and the big problem of contact resistance of ground wire wire clamp.

Simultaneously, when action bars head end lock had wire clamp, warning device was in open state automatically, when ground wire and charging equipment distance the time less than safe distance, can sound in advance and the light warning signal, wire clamp and ground wire action bars head end are threaded off automatically, reliably prevent charged hanging earthing conductor accident.
