Abstract
A hook type rapid connecting connector for an emergency power supply vehicle belongs to the field of emergency power supply devices. The hook type rapid connecting connector consists of a hook body, a user lead pressing module and an emergency power supply vehicle outgoing cable connecting terminal. An upper portion of the hook body is an N-shaped lateral-opening bending copper bar, and a lower portion of the hook body is provided with a fixed base. User lead pressing module is disposed on the fixed base. The user lead pressing module is composed of a pressing block and an adjusting screw which penetrates through the fixed base, wherein the pressing block can be fixed to the fixed base in an elevating manner through the adjusting screw, and a distance between the pressing block and a bending portion of the lateral-opening bending copper bar can be adjusted through rotation of the adjusting screw. Longitudinal axes of the fixed base, the hook body and the user lead pressing module coincide with each other. A first fixing screw is disposed on an outer side of the lateral-opening bending copper bar at a non-opening side, and thus the emergency power supply vehicle outgoing cable connecting terminal is formed. The hook type rapid connecting connector can reliably and fixedly connect an emergency power supply vehicle cable with a user low-voltage outgoing lead in a convenient and rapid manner, and guarantees quality of connection.
Description
Technical field
The utility model belongs to the loop apparatus field that is used for Emergency Power, relates in particular to a kind of quick power connection that is used for the emergency power supply car.
Background technology
Along with the further acceleration of Chinese Urbanization and rural urbanization process, 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 users' such as resident, enterprise normal electricity consumption, power supply department broad research, the advanced electric equipment of introduction and technology.Wherein important measures is special user's (such as hospital, bank, security, confidential departments, fire-fighting, one-level electricity consumption client such as speedily carry out rescue work) configuration emergency power supply car exactly, overhaul at distribution line, when needing inactive line, power supply department can be enabled the emergency power supply car 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 electric power, telecommunications, municipal administration, highway construction, plumbing air feed, flood control again for the sudden power failure of relevant department provides good interim power supply guarantee, speedily carry out rescue work and 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 utilization experience in recent years shows, adopting the emergency power supply car to send out/exist when power some tangible problems to the user, summary 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 the emergency power supply car is reached the spot, wait power supply department professional (power supply department administration equipment) or user electrician's (subscriber equipment) to draw back the high and low pressure service entrance switch of customer substation, hang up properly earth connection, take bolt, nut that the low pressure busbar tightens the bus copper bar then apart, the outlet cable of emergency power supply car could be received on user's low pressure busbar, just can be generated electricity then, power.
If run into fastening bolt, nut corrosion on the low pressure busbar, perhaps user electrician (the low pressure busbar does not adopt the screw that installs and fixes of the above big 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, greatly the delayed recovery supplying time.
(2) emergency power supply car outlet cable joint and user's low pressure busbar joint do not match, influence connection speed between the two:
The joint chi footpath of emergency power supply car outlet cable is bigger if user's low pressure busbar joint adopts little chi footpath bolt, and contact resistance was bigger when both were connected, and was the weak spot of supply line herein, and heating can be more serious; If user's low pressure busbar joint adopts is large size bolt and the joint chi of emergency power supply car outlet cable is directly compared than little, and both can not connect like that, cause emergency service to carry out.
(3) emergency power supply car outlet cable and user's low pressure outlet lead do not match, influence 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 emergency power supply car output cable is generally copper conductor, copper cable directly is wrapped in the connection resistance that can not guarantee on the overhead wire between the two within the limits prescribed, and material difference between the two, directly be articulated and connected is that safety regulations institute is unallowed, so for this type of user, can only find its service entrance switch (needing sometimes to search several kms or longer distance along its overhead transmission line in the open air) along overhead transmission line, the lead of its former overhead wire in end of incoming cables is removed, the emergency power supply car is reached the position (position at its service entrance switch place is not suitable for driving into of emergency power supply car sometimes) at service entrance switch place, connect the outlet cable of emergency power supply car again, bring difficulty for this type of user's emergency service, lose the opportunity of emergency service and the meaning of use emergency power supply car sometimes.
So in the on-the-spot emergency service work of reality, press for the outlet cable and the low pressure busbar of customer substation or the quick problem that is connected and guarantees quality of connection between the low pressure outlet that solve the emergency power supply car.
