Description
Technical field
The invention belongs to the loop apparatus field for Emergency Power, particularly relate 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 urban electric power supply requirement, in continuous increase, is also improving constantly the requirement of the reliability of power supply.For ensureing the normal electricity consumption of the user such as resident, enterprise, power supply department is extensively studied, introduce advanced electric equipment and technology.Wherein important measure is exactly for special user's one-level Electricity customers such as (such as hospital, bank, security, confidential departments, fire-fighting) speedily carrying out rescue work configures power supply vehicle of meet an emergency, at power distribution line maintenance, when needing inactive line, power supply department can enable power supply vehicle of meet an emergency immediately, guarantees that user can continue electricity consumption.
Authorized announcement date is on December 19th, 2007; Authorization Notice No. is disclose one " moving emergency supply vehicle " in the Chinese utility model patent of CN200992166Y; this moving emergency supply vehicle comprises automobile chassis, driver's cabin, compartment etc.; main feature is that automobile chassis is provided with compartment, Nei You control room, compartment, generating set, alternating current-direct current lighting device, distribution control device and cable hank control room; Be provided with hydraulic leg lowering or hoisting gear under compartment, cable hank has cable reel installation in control room.This moving emergency supply vehicle that different size is provided, good temporary power guarantee can be provided for the sudden power failure of relevant department, electric power, telecommunications, municipal administration, highway construction, plumbing air feed, flood control can be met again, speedily carry out rescue work and power supply needs that the relevant departments such as army, fire-fighting speedily carry out rescue work for field work and carry on construction work at night.
But field experience in recent years shows, adopt power supply vehicle of meet an emergency send out to user/power time there are some obvious problems, sum up get up to mainly contain following some:
(1) fixed screw dismantling low-voltage busbar is consuming time longer, causes power interruption time longer:
After power supply vehicle of meet an emergency is reached the spot, power supply department professional (power supply department administration equipment) or user electrician's (subscriber equipment) is waited to pull open the high and low pressure service entrance switch of customer substation, hang up properly earth connection, then the bolt of fastening bus bar copper row in low-voltage busbar, nut is taken apart, could the outlet cable of power supply vehicle of meet an emergency be received in user's low-voltage busbar, then just can carry out generating electricity, powering.
If run into the fastening bolt in low-voltage busbar, nut corrosion, or with special extracting tool, (low-voltage busbar does not adopt the installation fixed screw of more than M10 large gauge to user electrician usually, the sleeve needing specification with it supporting or Open jaw type wrench, and electrician only carries the instruments such as the screwdriver can only dismantling the small dimension screws such as M3, M5 usually), the fixed screw of dismounting low-voltage busbar is consuming time longer, the time of delayed recovery greatly being powered.
(2) power supply vehicle of meet an emergency outlet cable joint does not mate with user's low-voltage busbar joint, impact connection speed between the two:
If user's low-voltage busbar joint adopts the joint chi footpath of little chi footpath bolt and power supply vehicle of meet an emergency outlet cable comparatively large, when both are connected, contact resistance is comparatively large, is the weak spot of supply line herein, and heating can be more serious; If the joint chi footpath of what user's low-voltage busbar joint adopted is large size bolt and power supply vehicle of meet an emergency outlet cable is compared than little, both can not connect like that, cause emergency service to carry out.
(3) power supply vehicle of meet an emergency outlet cable does not mate with user's low-pressure line-outgoing wire, impact connection speed between the two:
When the transformer station of user is pole transformer, its low pressure output lead is generally overhead wire form, because overhead wire is generally aluminum core line, and power supply vehicle of meet an emergency output cable is generally copper conductor, copper cable is directly wrapped in the contact resistance that overhead wire can not ensure 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, its service entrance switch (sometimes needing to search a few km or longer distance along its overhead transmission line in the wild) can only be found along overhead transmission line, the wire of former for its end of incoming cables overhead wire 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 the outlet cable of power supply vehicle of meet an emergency again, difficulty is brought to the emergency service of this type of user, lose the opportunity of emergency service sometimes and use the meaning of power supply vehicle of meet an emergency.
Therefore in the on-the-spot emergency service work of reality, the outlet cable of power supply vehicle of meet an emergency in the urgent need to address and the quick problem being connected and ensureing quality of connection between the low-voltage busbar of customer substation or low-pressure line-outgoing.
