Description
Technical field
The invention belongs to the loop apparatus field for Emergency Power, relate in particular to a kind of quick power connection for power supply vehicle of meet an emergency.
Background technology
Along with the further acceleration of Chinese Urbanization and the Course of Urbanization, city size is in continuous expansion, and the urban electric power supply requirement is in continuous increase, and the requirement of the reliability of power supply is also being improved constantly.For guaranteeing the users' such as resident, enterprise normal electricity consumption, power supply department broad research, the advanced electric equipment of introduction and technology.Wherein important measure is special user's (such as hospital, bank, security, confidential departments, fire-fighting, the one-level electricity consumption client such as speedily carry out rescue work) configuration power supply vehicle of meet an emergency exactly, at power distribution line maintenance, when needing inactive line, power supply department can be enabled power supply vehicle of meet an emergency immediately, guarantees that the user can continue electricity consumption.
Granted publication day is on December 19th, 2007, Granted publication number discloses a kind of " moving emergency supply vehicle " in the Chinese utility model patent of CN 200992166Y, this moving emergency supply vehicle comprises automobile chassis, driver's cabin, compartment etc., main feature is that automobile chassis is provided with the compartment, and control room, generating set, alternating current-direct current lighting device, distribution control device and cable hank control room are arranged in the compartment; The hydraulic leg lowering or hoisting gear is installed under the compartment, and cable hank has cable reel installation in the control room.This moving emergency supply vehicle that different size is provided, can can satisfy again electric power, telecommunications, municipal administration, highway construction, plumbing air feed, flood control for the sudden power failure of relevant department provides good interim power supply guarantee, speedily carry out rescue work and the relevant departments such as army, fire-fighting are used for the power supply needs that field work is speedily carried out rescue work and carried on construction work at night.
Yet field experience in recent years shows, has some obvious problems when adopting power supply vehicle of meet an emergency to send out/power to the user, sum up get up to mainly contain following some:
(1) fixed screw of dismounting low pressure busbar is consuming time longer, causes the power failure time longer:
After power supply vehicle of meet an emergency is reached the spot, wait power supply department professional (power supply department administration equipment) or user electrician's (subscriber equipment) to pull open the high and low pressure service entrance switch of customer substation, hang up properly earth connection, then take bolt, nut that the low pressure busbar tightens bus bar copper row apart, the outlet cable of power supply vehicle of meet an emergency could be received on user's low pressure busbar, then just can be generated electricity, power.
If run into fastening bolt, nut corrosion on the low pressure busbar, perhaps user electrician (the low pressure busbar does not adopt the installation fixed screw of the above large specification of M10 usually with special extracting tool, need supporting sleeve or the Open jaw type wrench of specification with it, and the electrician only carries the instruments such as screwdriver of small dimension screws such as can only dismantling M3, M5 usually), the fixed screw of dismounting low pressure busbar is consuming time longer, with time of delayed recovery power supply greatly.
(2) power supply vehicle of meet an emergency outlet cable joint and user's low pressure bus joint do not mate, impact connection speed between the two:
The joint chi footpath of power supply vehicle of meet an emergency outlet cable is larger if user's low pressure bus joint adopts little chi footpath bolt, and when both are connected, contact resistance is larger, is the weak spot of supply line herein, and heating can be more serious; Be that the joint chi footpath of large size bolt and power supply vehicle of meet an emergency outlet cable is compared than little if user's low pressure bus joint adopts, both can not connect like that, cause emergency service to carry out.
(3) power supply vehicle of meet an emergency outlet cable and user's low-pressure line-outgoing wire do not mate, impact connection speed between the two:
when user's transformer station is pole transformer, its low pressure output lead is generally the overhead wire form, because overhead wire is generally aluminum core line, and the power supply vehicle of meet an emergency output cable is generally copper conductor, copper cable directly is wrapped in the contact resistance that can not guarantee on overhead wire between the two within the limits prescribed, and material is different between the two, directly be articulated and connected is that safety regulations institute is unallowed, therefore for this type of user, can only find its service entrance switch (sometimes needing to search several kms or longer distance along its overhead transmission line in the open air) along overhead transmission line, the wire of its former overhead wire in end of incoming cables is removed, power supply vehicle of meet an emergency is reached the position (position at its service entrance switch place is not suitable for driving into of power supply vehicle of meet an emergency sometimes) at service entrance switch place, connect again the outlet cable of power supply vehicle of meet an emergency, bring difficulty for this type of user's emergency service, lose sometimes the opportunity of emergency service and the meaning of use power supply vehicle of meet an emergency.
Therefore in the on-the-spot emergency service work of reality, the quick problem that is connected and guarantees quality of connection between the outlet cable of power supply vehicle of meet an emergency in the urgent need to address and the low pressure busbar of customer substation or low-pressure line-outgoing.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of coupling type power supply vehicle of meet an emergency and accesses fast joint, it adopts hook structure and pole transformer to make the low-pressure line-outgoing of gram case be connected, only need remove the insulating barrier of part wire during use, can be directly that the cable of power supply vehicle of meet an emergency and user's low-pressure line-outgoing wire is reliably affixed, connection procedure is convenient, fast, the quick connection between the cable of realizing power supply vehicle of meet an emergency and customer substation low-pressure line-outgoing, guarantee quality of connection.
