Description
Technical field
The utility model relates to electrical equipment technical fields, the specifically anti-down lead wire of prefabricated.
Background technique
The important pivot that 10KV distribution transforming rack is connected as distribution line, reliability of operation, stability and its important,
Once breaking down, wide coverage influences greatly, and loss is inestimable, and repairing will employ engineering truck, inconvenient for operation, when
Between it is long, it is at high cost.The lead wire of traditional distribution transforming rack is usually to make, and time-consuming and laborious, the duration is longer, and quality is due to people
It is different, be easy to produce because scene crimping deformation, copper-aluminium transition, expand with heat and contract with cold or shake reason cause connection end generate heat loosening etc. ask
Topic, and the product to complete is difficult to carry out electric performance test due to field condition, usually not after testing just at once
Installation, quality do not have any guarantee, and existing performance hidden danger is to lead to the key factor of failure；The connecting pin of traditional lead wire
Head deforms larger after crimping, can generate most weak spot, and effective area of passage is typically only the 65-75% of nominal cross section product,
It is the hidden danger point to break down；The connection end of traditional lead wire, the general insulation processing mode for using heat-shrink tube or cold shrink tube,
Weatherability is poor, and the coefficient of thermal expansion and contraction of heat-shrink tube or cold shrink tube is different from the coefficient of thermal expansion and contraction of lead wire end oversheath,
It is easy to cause to seep water due to expanding with heat and contract with cold causes junction to generate crack in use process.
In addition, distribution transforming rack carries out grid maintenance at present, it is all inspection after first closing the power supply system of distribution transforming rack area
Repairing personnel, high altitude operation is overhauled again, and without anti-down for electric treatment, this mode, it cannot be guaranteed that the peace of construction personnel
Entirely, because aerial backbone will necessarily wiring register one's residence, and certain customers (such as school, market, factory) will be installed generator, with
Normal operation of the normal power supply without influencing electric appliance when guaranteeing to have a power failure, can exist when power failure to fall to power from user's house generator
Make the phenomenon that still charging on backbone on to aerial backbone, if construction personnel is breaking the power supply system on backbone
Afterwards, it is no it is anti-down for electric treatment in the case where, overhauled rashly, certainly will have great security risk, or even have maintenance
Personnel are in order to efficiently act, and at all without grounding, even more threaten its life security, therefore carry out to lead wire anti-down
It is most important for electric treatment.Currently, carrying out the anti-down mode for electric treatment to lead wire is usually first to remove one section to lead wire
Oversheath forms Naked line position, is then grounded and anti-down power supply at Naked line position, but the long-term Naked dew of lead wire will certainly be led
Cause such as is cocked off, gets an electric shock at the security risks, and while overhauling circuit every time shells lead wire line again, is grounded, operates also pretty troublesome therefore anxious
It needs one kind not only with anti-down power supply unit to facilitate ground connection but also the lead wire of normal use can be facilitated, is mounted on and is frequently necessary to examine
The position (such as distribution transforming rack area) repaired facilitates progress anti-down for electric treatment in maintenance, can be as normal when not overhauling
Lead wire use.
