Description
Technical field
This utility model belongs to electronic communication field, specifically, is related to a kind of practical earth lead of indoor GIS terminal.
Background technology
As urban distribution network is put cable underground popularization, various high-voltage ring main units, high tension cable merogenesis case and high tension cable branch
Case is come into operation successively, has beautified city, it is to avoid wire breaks, single-phase earthing when the accident of human electric shock that occurs, because of high pressure
Ring main unit, high tension cable merogenesis case and high voltage cable branch box self-defect, overhaul during high tension cable trouble shooting to ensure
, there is no human casualty accident, it is necessary to large-area power-cuts in the inherently safe of personnel, this brings huge damage to enterprise and society
Lose.Current city electrical network gradually enters ground, and what ring main unit, cable branch box and cable distribution box had become the connection of underground electrical network must
Palpus carrier, into the main frame of Urban Underground electrical network, electric current is gradually shunted by these main frames, in beautifying urban environment
While meet the needs of user's actual power.
Ring main unit is circuit breaker trolley and ground connection one simultaneously, meets demand for grounding, when in ring main unit when overhauling at ordinary times
When earthing mechanism failure needs inspection earthing mechanism, it is impossible to realize closing ground wire operation, have to by reserving in cable branch box
Ground connection or all fronts interruption maintenance at ground pin.Cable distribution box endogenous cause of ill is connected using cable T connector, it is impossible to installing ground connection
Line, is had to be grounded using this earth lead, meets service requirements, can just ensure that the personal safety of service work personnel, institute
With this earth lead huge market demand, the economic worth and social efficiency of generation is considerable, be worth in same type transformer station and
Large, medium and small city cable enters promoting the use for ground.
Existing cable branch box Special grounding wire is found out：Ground connection must be reserved in the cable branch box of earth lead installing to insert
Head, must reserve a certain distance, and certain insulation, and cabinet space will be kept to reach with feeder pillar between reserved plug
Certain volume, otherwise ground pin can be because being short-circuited failure with casing insulation distance deficiency.
Existing indoor gas-insulating and fully-enclosed (GIS, gas insulated substation) terminal and outdoor terminal
Between by cable connection, at indoor GIS terminal using high tension cable T connector front connector and rear joint to be connected to transformer station female
On the main line of line or high-tension line, outdoor terminal is connected directly between in outlet or on branch line by cable, so as to realize high-tension electricity
The flexible T of cable main line connects, and meets the power demands of user.
Fig. 1 is a 35kV Substation Bus Arrangement figure of certain power supply administration, and the station is modular transformer substation, two power supplys of 35kV
Cable only has chopper and bus bar side disconnecting switch, without circuit disconnecting link and circuit ground knife.Line maintenance and cable fault inspection every time
Repair installing peace to arrange, because according to National Standard of the People's Republic of China《Electric power safety working regulation》Power plant and power transformation
Stand 6.4.4 bars regulation in electric part (GB26860-2011)：Each side of possible power transmission to power failure equipments should all be grounded and according to
China Nanfang Grid Co., Ltd《Electrical safe working order》(Q/CSG510001-2015) specify in 7.4.1.15：Make
Industry personnel should be in operation in the protection domain of earth lead.Forbid it is uneven on without ground wire or grounding wire mounting in the case of inlet wire have a power failure
Upkeep operation.
In the past at transformer station's electric power incoming line XXX line outlet lower cabinet doors, cable broke down twice, it is per treatment be all by
Full station equipment has a power failure, and all loads onto earth lead in each side that may be sent a telegram here.Because being that whole station has a power failure, the life of the supplied user in the station, life
The livelihood issues such as product all receive tight test, cause to have a strong impact on to the power supply reliability and business efficiency of enterprise.
Existing earth lead product earth lead, in use occur winding, due to earth lead metal part it is longer, compared with
Weight, insulating bar are also longer, and operation is laborious, easily make a mess of the screw thread of the screw rod of equipment during assembly and disassembly earth lead, but due to
Conductor contact position is connected with internal sealing plug, is not suitable for screw rod various sizes of at the high tension cable T connector of various models, is suitable for
Scope is little.Advantage：Meet the actual demand of equipment, easily shunt, contact resistance is little.Earth lead easily occurs in use by spiral shell
The phenomenon that bolt silk mouth is damaged, earth resistance are somewhat big, it is impossible to quick to shunt.
