Abstract
The utility model relates to a branch line device of a power distribution network, in particular to branch line fault separating and segmenting equipment of a power distribution network. The technical scheme of the equipment is as follows: a switch cross arm is arranged on an electric pole, a demarcation switch is fixed on the switch cross arm, a demarcation switch controller is connected with the demarcation switch by a data wire, and the demarcation switch controller is fixed on the electric pole. The equipment has the beneficial effects that: the user demarcation switch is used as the segmenting equipment of a 10-kv power distribution line and a T wire connecting line; when the T wire connecting line is in fault, the equipment can timely judge types of the fault and quickly cut off the T wire connecting line without affecting the normal power supply of trunk lines and adjacent lines; moreover, power failure of important users due to the line faults of other users can be prevented.
Description
One, technical field:
The utility model relates to a kind of power distribution network branched line device, particularly relates to a kind of power distribution network branched line Fault Isolation staging device.
Two, background technology:
When 10kV overhead transmission line T connects user inside and breaks down, when fault occurs in house lead in or occurs in house lead in switch inboard and when subscriber switch and transforming plant protecting mismate, all can cause transformer station to go out the wiretap breaking.As fault character is permanent, and unsuccessful reclosing then thus, presses user's accident will involve whole piece line outage in one, influences the normal electricity consumption of responsible consumer in the circuit, causes economic loss.According to statistics, this class involves accident and accounts for 20%～30% of the total accident of power distribution network, and some place is higher than regular meeting.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, a kind of power distribution network branched line Fault Isolation staging device is provided, when T link outlet fault, timely failure judgement type, fast shut-off T link does not influence the normal power supply of basic routing line, adjacent lines.
Its technical scheme is: be provided with the switch cross-arm on electric pole, be fixed with demarcation switch on the switch cross-arm, the demarcation switch controller connects demarcation switch by data wire, and described demarcation switch controller is fixed on the electric pole.
Above-mentioned switch cross-arm is fixed on the electric pole by anchor ear.
Above-mentioned demarcation switch controller is fixed on the electric pole by anchor ear.
It is suitable for and is installed on the point of incoming cables that 10kV overhead wire T connects user's branch line, is applicable to that isolated neutral system, neutral point are through low resistance grounding system and neutral by arc extinction coil grounding system.
The beneficial effects of the utility model are: the user demarcation switch is as the staging device of 10kV distribution line and T link, when T link outlet fault, timely failure judgement type, fast shut-off T link, do not influence the normal power supply of basic routing line, adjacent lines, prevent the power outage that responsible consumer causes because of other subscriber's line fault.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Five, embodiment:
In conjunction with the accompanying drawings, the utility model will be further described, and its technical scheme is: be provided with switch cross-arm 2 on electric pole 1, be fixed with demarcation switch 4 on the switch cross-arm 2, demarcation switch controller 5 connects demarcation switch 4 by data wire, and described demarcation switch controller 5 is fixed on the electric pole 1.Above-mentioned switch cross-arm 2 is fixed on the electric pole by anchor ear 3, and above-mentioned demarcation switch controller 5 is fixed on the electric pole by anchor ear 3.
In conjunction with the present situation of company's distribution system structure, choose east burst at the seams Fenhe River road branch line, line taro state, development zone branch line, electric power garden, two wires, Dengzhou branch line totally 3 branch lines as research object, closed test success.When 10kV overhead transmission line T connect user inside and breaks down, system can finish fault excision and isolating automatically.
