Description
Technical field
The present invention relates to high-tension apparatus monitoring fields, and in particular to a kind of converting station electric power high-tension apparatus overheating protection is anti-error
Device.
Background technique
The overheat protective technology scheme of power high voltage equipment, has three ways, such as following: 1) will be high at present in traditional substation
It presses equipment to have a power failure, does the electrical tests such as corresponding D.C. resistance, leakage, insulation, pressure resistance；2) by operation maintenance personnel carry it is infrared heat at
As equipment to substation carries out artificial thermometric scanning to high-tension apparatus by platform；3) the infrared robot power transformation yard newly carried out at present
Ground inspection.In three of the above technical solution, the first, which need to have a power failure just, be can be carried out, and can not carry out online detecting and protection.Second
Manual operation is needed, when infrared measurement of temperature equipment itself fail or quality problems, thermometric is not punctual, can not be live to used red
Outer temperature measuring equipment carries out may cause erroneous judgement, and low efficiency, the time is long, is also influenced by ambient weather, nothing to mark temperature correction
24 hours continuous on-line detections of method.The third infrared measurement of temperature robot is equally existed when event occurs for infrared measurement of temperature equipment itself
Barrier or quality problems, thermometric is not punctual, can not scene to using infrared measurement of temperature equipment carry out to mark temperature correction, may cause
The problem of erroneous judgement, and robot ambulation is slow, the complete whole transformer station of inspection takes a long time, and walking landform requires flat
Smooth, the gradient that cannot walk is larger, green lawn or many roads across cable duct, door column etc, can not also carry out within 24 hours
Online detecting and protection.
In conclusion be now badly in need of one kind can on-line continuous to high voltage device of transformer station carry out overheating fault examined online
It surveys and the device of protection, can guarantee that this device is capable of measuring accurately again, prevent from being not allowed due to measurement or cause to having occurred
The high-tension apparatus erroneous judgement of thermal fault be it is normal, damaged, or made due to that cannot handle in time so as to cause overheat high-tension apparatus
At being overheating fault equipment by the low high-tension apparatus error detection of qualified normal high-tension apparatus and degree of superheat, cause to judge by accident
Serious consequence disconnected, that even cause second protection to malfunction, this problem of the application very good solution, can be converting station electric power
The safe and economical operation of high-tension apparatus provides a strong guarantee.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of converting station electric power high-tension apparatus overheating protection error-proof device,
It solves due to sole mass or misoperation in its use process, or is asked using time permanent aging or environmental factor etc.
Topic all may cause the problem of thermometric is not allowed, may cause erroneous judgement or maloperation.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of converting station electric power high-tension apparatus overheating protection error-proof device, including several infrared thermal imagings being arranged in substation
Unit, the normal temperature corrector being equipped with infrared thermal imaging unit, the control list being set on the outside of power high voltage equipment
Member and high-tension apparatus protection location；Described control unit and infrared thermal imaging unit, normal temperature corrector and high-tension apparatus are protected
Shield unit is separately connected.
Further, the infrared thermal imaging unit includes the highly sensitive infrared thermal imaging probe of wide-angle, is set to probe bottom
The probe diverter in portion and for install probe equipment mounting rod.
Further, the normal temperature corrector includes normal temperature melting point bar, constent temperature heater and standard thermometer.
Further, the high-tension apparatus protection location includes alarm, switch separating brake protective loop and source-side switches.
Further, the power high voltage equipment includes transformer, capacitor, reactor, mutual inductor, arrester, switch,
Connect high-voltage conducting wires and connector.
Compared with the prior art, the invention has the following beneficial effects:
The present invention can converting station electric power high-tension apparatus occur various true overheating faults when accurately and effectively protected and
It prevents since infrared measurement of temperature equipment is in use due to sole mass problem or misoperation, or permanent using the time
Aging and environmental impact factor etc. cause thermometric to be not allowed to cause to miss to occurring what overheating fault equipment was alarmed and handled
Chance equally also prevents that normal device is caused to be mistaken as that overheating fault occurs, to issue false alarm signal, or even causes
The serious consequence of second protection malfunction.
