Description
Technical field
The utility model is related to switch cubicle technical field, especially a kind of breaker temperature on-Line Monitor Device.
Background technology
The vacuum circuit breaker of high-voltage board is the visual plant in electric power, power network, once occur accident, can cause it is local or compared with
The power failure of major region, thus equipment run one section when after or operation in must carry out necessary examination and maintenance, dynamic and static contact connects
There is a contact resistance when touching, between them, in normal operation, breaker primary conductive loop resistance, including contact resistance
It is stable, heat energy is produced by operating current for a long time, raises the temperature of appliance material, now, temperature rise is typically without departing from regulation
Scope, but galvanic circle once comes in contact bad, and contact resistance is excessive, and temperature rise can exceed setting, so as to accelerate dynamic and static touch
Head contact position oxidation, oxidation results cause contact resistance value to increase again, so promote heating to increase again, temperature increase, or even rise
Arcing is damaged.
Intellectuality is the trend of switchgear development, and on-line checking is the intelligentized principal character of switchgear.Online
The development and application of detection technique, improves the intelligence degree of switchgear operational management, accelerates switchgear operation shape
The feedback of the information of state, shortens the time of breakdown judge and processing, improves operating efficiency, reduces the economic damage caused by power failure
Lose, and to realize that unattended operation transformer station creates condition.

Device.It is many between current indoor breaker and the switch cubicle being matched therewith to be slidably connected by fingertip come shape for the ease of maintenance
Into through-flow major loop, and because of equipment assembling, maintenance or change, easily match somebody with somebody between finger of breaker and switch cabinet static contact
Conjunction problem, easily causes contact resistance increase, so as to cause temperature rise too high, causes through-flow problem or insulation fault.Therefore, it is breaking
The on-line monitoring of device fingertip junction temperature rise seems increasingly important.
The existing temperature measurement on-line mode of switchgear is wired thermometric mode, and it can not solve electronic component in high temperature
Under working stability sex chromosome mosaicism.Existing frequently-used method of testing is to draw the indirect temperature measuring point of selection tradition, copper test on copper bar
Temperature is arranged, common methods have：One is to stick on paraffin or temperature sense piece in indirect temperature measuring point, by artificial timed patrol, utilizes heat
The principle of conduction, judges temperature roughly according to the color change of the thawing degree of paraffin or temperature, dynamic/static contact is inferred indirectly
Temperature is connected, implements manual intervention.Two be, by artificial timed patrol, using hand-held infrared ray tester, to be surveyed by peep hole
The temperature of indirect temperature measuring point is tried, according to the test number of degrees, using the principle of heat transfer, dynamic/static contact connection temperature is inferred indirectly, it is real
Apply manual intervention.The shortcoming of these methods is that the temperature measured is not the temperature of dynamic/static contact junction, but is inferred indirectly
The temperature of dynamic/static contact junction, this temperature measured is easily disturbed by external condition and environment, is caused erroneous judgement, is unfavorable for breaking
The intelligent realization of road device.
