Description
Technical field
High voltage cable malfunction monitoring technical field is the utility model is related to, specially a kind of high voltage cable malfunction monitoring face
Template fault detector structure.
Background technology
A large amount of uses of high voltage cable at present so that the fault rate of cable also accordingly increases.Especially supplied in a plurality of cable
In electric system, such as occur bypassing the immediate leadership trip protection when, it may be difficult to judge specific failure cable, sometimes even all cables are complete
Portion remove do after pressure test could correct failure judgement cable, its workload is big, performance difficulty, is unthinkable, to this
It is necessary to design a kind of new detection device, each current supply circuit is monitored in real time, when line failure, can carries
Show or directly display failure cable, to improving operating efficiency, restore electricity has highly important meaning rapidly.
Panel type fault detector is mounted on power cable distribution line, case change, ring main unit, in feeder pillar, is used for
The device of fault current circulation is indicated, once short trouble occurs for circuit, track walker can be by the red alarm on indicator
It has been shown that, determines rapidly fault section, branch and trouble point, thorough to change blindness line walking in the past, and segmentation combined floodgate trial line charging searches event
The backwardness way of barrier, operating efficiency is greatly improved, shorten power off time, effectively improve power supply reliability and economic benefit.
Current panel type fault detector major function has：
1st, short circuit current police instruction：Short circuit current sensor carries out online to the high-tension cable being currently running at work
Detection, when line current meets or exceeds the setting valve of short circuit current, short-circuit sensor sends alarm signal and passed by optical fiber
It is defeated to arrive main frame, after main frame receives this signal, produce corresponding alarm indication signal；
2nd, grounding alarm indicates：The system works as ground path using the earth current of grounding sensor detection service cable
Middle electric current meets or exceeds when earth current starts alarming value and (can required to be adjusted before dispatching from the factory according to user), ground connection sensing
The alarm signal that device sends passes to main frame, after main frame receives this signal, produces corresponding alarm indication signal；
3rd, panel main frame indicates：Alarm lamp, SR are provided with panel main frame and button of testing oneself, panel main frame
Receive short circuit or grounding sensor is transmitted through next signal, LED sends red flare alarm；
(1) automatic reset system：After indicator sends alarm signal, if prosthetic is resetted in 24 hours,
Indicator can be resetted automatically.
(2) manual reset：, can be by being carried out by the SR on lower panel host panel after indicator produces alarm
Alarm is released, carries out manual reset.
(3) test：The system can carry out self-test work by the removing button on panel, to detect the function of the machine, even
The continuous removing button press on lower panel 2 seconds, the machine enter self-test state, and the green indicating lamp on all panels is glittering, exports
Relay adhesive, illustrate that working condition is normal.
For the panel type fault detector with above-mentioned monitoring function, the appearance one that it in use can be apparent
A little the problem of being inconvenient to use：Because fault detector belongs to panel type, need staff intuitively to indicating fault
The panel of device is observed, and is obtained by the light of short circuit current alarm lamp and grounding alarm indicator lamp change on panel
Fault message, but panel is directly exposed to staff and can also increase the impaired probability of panel in front, so Structure of need
Go to protect the panel of indicator, while observation of the staff to alarm lamp can't be influenceed and to button
Operation；And when panel carries out self-test, if the indicator lamp on panel does not have all light green light, prove indicating fault
Device there is a problem itself, now needs to be repaired the taking-up very easy from protection structure of panel main frame, can just protect
Card fault detector preferably carries out the malfunction monitoring of cable.
