Abstract
The utility model relates to a fault detecting device of power equipment, in particular to a lower voltage drawer-type switch cabinet fault potential detecting device. The technical scheme is that power temperature measuring pasters are arranged on each joint in a lower voltage drawer-type switch cabinet on the basis of an existing lower voltage drawer-type switch cabinet structure. The lower voltage drawer-type switch cabinet fault potential detecting device has the effects that failures can be displayed in time through temperature conversion before the drawer-type switch cabinet generates faults, attended inspectors can discover problems in the shortest time and eliminate the faults in bud states, fault detecting passivism due to unavailable normal detection of the drawer-type switch cabinet can be reduced, the faults in the drawer-type switch cabinet also can be stored in drawers of the drawer-type switch cabinet in a memory mode, maintenance and processing of fault points when in repair can be guaranteed, and contact temperature which can be detected only by an accurate infrared thermometric indicator can be displayed in a color change mode, which is convenient for maintaining and making corresponding processing.
Description
Technical field
The utility model relates to the failure detector of power equipment, especially relates to a kind of low voltage drawer switch cubicle potential faults checkout gear.
Background technology
At present, the employed drawer-type switch cabinet of each enterprise, it is a kind of novel product, quality problems can not appear generally in 1-2, and because the arbitrarily transposing property of drawer, also reduced the time that has a power failure, improved power supply quality, but after equipment operation 2 years, because factors such as loss, drawer switch cubicle connector is prone to blast, thereby cause whole transformer to have a power failure, caused huge cost allowance to enterprise, judged that reason is because the plug-in unit loose contact of drawer switch cubicle causes, but because the particularity of its equipment, under charged situation, can't and outside be electrically connected facility inspection to the components and parts in the drawer switch again, if with infrared thermometer also is the contact temperature that moved at that time can only be checked, can't under the situation of load change, detect correct temperature, more can't find out the hidden danger place in the drawer switch cubicle.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, provide a kind of can visual inspection, easy for installation and detected temperatures low voltage drawer switch cubicle potential faults checkout gear accurately.
Its technical scheme is: on the basis of existing low voltage drawer switch cubicle structure, each the contact place in the low voltage drawer switch cubicle is provided with electric power thermometric paster.
Effect of the present utility model is the drawer switch cubicle just can in time can be displayed fault by the conversion of temperature before breaking down, the personnel of patrolling and examining on duty can be pinpointed the problems in the shortest time, fault is got rid of in bud, reduced the drawer switch cubicle owing to can't normally detect the breakdown maintenance passivity of bringing, the fault of drawer switch inside can also be stored in the drawer of drawer switch cubicle with the form of remembering, guarantee maintenance and processing to the fault point in when maintenance, and the contact temperature that can only could detect with the accurate infrared thermometer situation with change color can be showed, the prompting staff improves the attention to this point, so that keep in repair and make corresponding processing.
Description of drawings
Accompanying drawing one is the structural representation of embodiment 1; Accompanying drawing two is structural representations of embodiment 2.
Embodiment:
Embodiment 1: with reference to accompanying drawing one, present embodiment mainly is that the switch copper busbar in the low voltage drawer switch cubicle and the junction of circuit breaker are provided with three electric power thermometric pasters, and the temperature value of three electric power thermometric pasters is respectively 60 ℃, 70 ℃, 80 ℃.
Embodiment 2: with reference to accompanying drawing two, present embodiment mainly is that the input/output port in the low voltage drawer switch cubicle or the junction of main plug-in unit and main copper bar are provided with three electric power thermometric pasters, and the temperature value of three electric power thermometric pasters is respectively 60 ℃, 70 ℃, 80 ℃.
Operation principle: electric power thermometric paster has been pasted at the contact place in the low voltage drawer switch cubicle, if each connector bad connection, will produce high temperature at the contact place, temperature sends electric power thermometric paster to, make the variable color of electric power thermometric paster temperature, operator on duty or the personnel of patrolling and examining can in time judge this plug-in unit according to the color of main copper bar paster and whether have fault, in order to accomplish to prevent in advance, and the variable color that can judge paster is because the excessive or loose contact of running load, when pasting the thermometric paster, select the thermometric paster of three kinds of temperature signals, formulate temperature paster blackening in the time of 60 ℃, paster flavescence in the time of 70 ℃, the principle that paster reddens in the time of 80 ℃, the staff just can judge out of order situation according to the color of paster very intuitively like this, indoor operating temperature adds that the temperature in the power distribution cabinet generally can be above 45 ℃, proof has problem if temperature is crossed the higher position, we improve our vigilant in the time of can being defined in 60 ℃ of variable colors, 70 ℃ paster never has that variable color proves because excessive causing of load in this loop, if find 70 ℃ of paster variable colors gradually, so just proof will be strengthened paying attention to patrolling and examining of this point, if after 70 ℃ of paster variable colors, 80 ℃ of pasters never have variable color, so just prove that connector may go wrong, if operation a period of time 80 ℃ of paster variable colors afterwards, prove that promptly whole operation needs shut-down (breakdown) mainteance, though this temperature is unlikely to allow the junction of drawer switch plug-in unit be exploded, but the displacement problem has taken place in the inner member of contact, should try every possible means to arrange to have a power failure or load is transferred to back-up circuit, just should paste a slice thermometric paster in the place of variable color again if can not stop to transfer load, and strengthen paying attention to and observing, if 80 ℃ never redden after in the stickup, though can illustrate that so plug-in unit problem occurred and still can also use a period of time, if redden or after little one or two, redden after sticking at once, so just should take urgent measure plug-in unit is changed, if detect with infrared thermometer this moment, temperature shows may also not have 80 ℃, be because the precision of infrared thermometer is not good enough on the one hand, be because the present load of this contact has lowered on the other hand, so be difficult to make correct external connector temperature with the infrared thermometer survey.
