Description
Technical field
The present invention relates to a kind of grounding wire device, more particularly to a kind of transformer station is with portable grounding wire device and user
Method.
Background technology
The engineers and technicians of transformer station, to substation equipment such as：Transformer, transformer, switch, arrester etc. are examined
When repairing or testing, it is necessary to be to have to carry out under good reliable ground state in the equipment to overhauling or testing, otherwise connect
Ground is bad, and the sensation of numb shortcake just occurs when staff is with hand contact arrangement, and severe one is induced electric bullet once, because residual electricity
Pressure is higher, nervous when people contacts induced voltage, and personal grain shrinks, especially abnormally dangerous in work high above the ground.
The reason for causing induced voltage is as follows：
1st, the equipment component of power failure is overhauled and during maintenance work, frequently encounters also equipment component and do not have a power failure normally
Operation, due to the trend on dead line and live wire road, such as intersect or during a parallel segment distance, in live wire road magnetic fields
Under, the circuit of brownout has also just taken certain voltage with being connected equipment and has been referred to as induced electricity.
2nd, the filth due to atmosphere and the oxidation corrosion of itself so that circuit applies last layer filth or rust with being connected equipment
Layer is lost, filthy or corrosion layer is poorer than metallic conduction performance, so-called to be referred to as insulating compared to there is certain resistance；In temperature than relatively low
Under conditions of, sleety weather can also make circuit apply last layer thin ice with being connected in equipment, or insulation.
Cause to be grounded the reason for bad as follows：
Prior art uses the device being grounded to fix a hook on a longer insulating bar（Dop）, hook
Contact surface be streak-like planar structure, be connected to ground wire on hook, staff hangs over hook in the circuit being connected with power failure equipments
On, ground wire is connected by wiring dop with earth mat, you can carry out maintenance work.Seem ground wire to connect, due to hook and line
Road is plane contact, it is not easy to overcomes the influence of molecule insulating barrier or thin ice insulating barrier caused by filthy and oxidation corrosion
Influence, because filth, oxidation corrosion layer, thin ice insulating barrier do not destroy completely, then circuit be connected environment division with
Ground wire also remains certain voltage so that circuit again by the resistance value formed by this section of oxide layer separate and（It is approximate
It is breaking over the ground）It is sensed powered, there are slightly numb sensation, severe one when examining and clean examined human contact and cleaning equipment
By bullet once, moment completely without, after a while again above-mentioned phenomenon occurs, here it is the effect that induced voltage rises.
Grounding wire pole used in power station staff operation at this stage be there are problems that following：
1st, grounding wire pole hook used in each transforming plant primary equipment is not suitable for sleety weather change needed in equipment
Ground connection, the thin ice formed, it is not suitable for the oxide layer that equipment runs the appearance that influenced each other for a period of time with the filth of air yet, makes
It is bad into being grounded, certain threat is formed to the safety of staff.
2nd, substation's grounding wire pole is different different in size because of operational outfit voltage class, and with rear ground wire again
It is entangled on bar and puts irregular, is chronically exposed to and outer has worn unavoidably.
3rd, from master control room line bar storage place is inconvenient to the transport of required operational grounding scene, and it is also inconvenient to use
Profit.
The content of the invention
In view of the shortcomings of the prior art, the invention provides transformer station portable grounding wire device and user
Method, the present apparatus and method, no matter can have on circuit under any synoptic climate, non-oxidation layer and can use during ice coating, really
Circuit is protected（Bus）It is good with ground contact, it can prevent burst incoming call from carrying out electrostatic with what is sensed, ensure that and set in power failure
The personal safety of staff on standby upper and circuit.
