Description
Technical field
This utility model relates to a kind of grounding wire device, particularly to the portable grounding wire device of a kind of transformer station.
Background technology
The engineers and technicians of transformer station, to substation equipment such as: transformator, transformer, switch, spark gap etc. are examined
When repairing or test, it is necessary to be to the equipment that overhauls or test have under good reliable ground state and carry out, otherwise connect
Ground is bad, staff catch tactile equipment time arise that the sensation that fiber crops are crisp, severe one sensed electricity bullet once because residual electricity
Pressing higher, the psychentonia when people contacts induced voltage, person grain shrinks, especially abnormally dangerous in work high above the ground.
The reason causing induced voltage is as follows:
1, the equipment component having a power failure is overhauled and during maintenance work, be frequently encountered by also equipment component and do not have a power failure normally
Run, due to the trend of dead line Yu live wire road, during such as intersection or a parallel segment distance, at live wire road the action of a magnetic field
Under, the circuit of brownout is also referred to as faradism with regard to certain voltage on band with being connected equipment.
2, due to atmospheric filth and the oxidation corrosion of self so that circuit applies last layer filth or rust with being connected equipment
Erosion layer, filth or corrosion layer are poorer than metallic conduction performance, compare and have certain resistance, and so-called being referred to as insulate；Relatively low at temperature ratio
Under conditions of, sleety weather also can make circuit and apply last layer thin ice with being connected on equipment, it is possible to for insulation.
The reason causing ground connection bad is as follows:
Prior art uses the device of ground connection to be to fix a hook (dop), hook on a longer insulating bar
Contact surface be streak-like planar structure, hook is connected to ground wire, hook is hung over the circuit being connected with power failure equipments by staff
On, ground wire is connected with earth mat by wiring dop, maintenance work can be carried out.Seem ground wire to connect, due to hook and line
Road is plane contact, it is not easy to overcome impact or the thin ice insulating barrier of the molecule insulating barrier that filthy and oxidation corrosion brought
Impact, owing to filth, oxidation corrosion layer, thin ice insulating barrier destroy the most completely, then circuit be connected environment division with
Earth lead also remains certain voltage so that circuit is cut off and (approximation by the resistance value formed by this section of oxide layer again
Open circuit over the ground) sensed charged, check and clean human contact and be examined and also have slightly numb sensation, severe one during cleaning equipment
By bullet once, moment completely without, there will be the most again above-mentioned phenomenon, here it is the effect that induced voltage is risen.
Grounding wire pole used by present stage power station operated by personnel also exists following problem:
1, not to be suitable for sleety weather change required on equipment for grounding wire pole hook used by each transforming plant primary equipment
Ground connection, the thin ice of formation, be not suitable for equipment yet and run the filth of a period of time and air and influence each other the oxide layer occurred, make
Become ground connection bad, the safety of staff is constituted certain threat.
2, substation's grounding wire pole is different different in size because running equipment electric pressure, and with rear ground wire again
It is entangled on bar and puts irregular, be chronically exposed to and outer worn and torn unavoidably.
3, from master control room ground wire bar storage place to action required ground connection scene transport inconvenience, also inconvenience is used
Profit.
