Description
Technical field
The present invention relates to a kind of grounding wire device, particularly to one transformer station portable grounding wire device and using method.
Background technology
The engineers and technicians of transformer station, to substation equipment such as: when transformator, transformer, switch, spark gap etc. overhaul or test, necessarily to the equipment that overhauls or test have under good reliable ground state and carry out, otherwise ground connection is bad, staff catch tactile equipment time arise that the sensation that fiber crops are crisp, severe one sensed electricity bullet is once, because residual voltage is 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, it is frequently encountered by also equipment component and does not have a power failure properly functioning, trend due to dead line Yu live wire road, during such as intersection or a parallel segment distance, under the action of a magnetic field of live wire road, 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 corrosion layer with being connected equipment, and filth or corrosion layer are poorer than metallic conduction performance, compare and have certain resistance, and so-called being referred to as insulate；At temperature ratio under conditions of relatively low, sleety weather also can make circuit and be connected on equipment to apply last layer thin ice, it is possible to for insulation.
The reason causing ground connection bad is as follows:
The device of prior art employing ground connection is, a longer insulating bar is fixed a hook (dop), the contact surface of hook is streak-like planar structure, ground wire it is connected on hook, hook is hung on the circuit being connected with power failure equipments by staff, ground wire is connected with earth mat by wiring dop, maintenance work can be carried out.Seem ground wire to connect, owing to hook and circuit are plane contact, it is not easy to overcome impact or the impact of thin ice insulating barrier of the molecule insulating barrier that filthy and oxidation corrosion brought, due to filth, oxidation corrosion layer, thin ice insulating barrier destroys the most completely, then circuit also remains certain voltage with being connected environment division with earth lead, by the resistance value partition by this section of oxide layer formation, (approximating open circuit over the ground) is sensed charged again to make circuit, inspection and cleaning human contact also have slightly numb sensation when being examined with cleaning equipment, severe one is 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, grounding wire pole hook used by each transforming plant primary equipment is not suitable for sleety weather change required ground connection, thin ice of formation on equipment, it is not suitable for equipment to run the filth of a period of time and air and influence each other the oxide layer occurred yet, cause 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 is entangled in again with rear ground wire and puts irregular on bar, is chronically exposed to and outer has worn and torn unavoidably.
3, from master control room ground wire bar storage place to action required ground connection scene transport inconvenience, use the most not convenient.
Summary of the invention
The deficiency existed in view of prior art, the invention provides transformer station portable grounding wire device and using method, this device and method, can be under any synoptic climate, no matter have on circuit, non-oxidation layer and can using during ice coating, ensure that circuit (bus) and ground contact are good, being possible to prevent burst incoming call with sensed carry out electrostatic, it is ensured that the personal safety of staff in power failure equipments and on circuit.
