Abstract
The utility model discloses a trip-out matrix test box for transformer protection, comprising a test box housing. The test box housing is provided with a plurality of connecting terminals, the connecting terminals are provided with corresponding supervision indication lamps in sequence, and the supervision indication lamp with a plurality of different colors are employed. According to the trip-out matrix test box for transformer protection, all test wiring is completed in one time, all trip-out outlet circuits are monitored for transformer protection, integral comparison is provided, the trip-out matrix correctness for transformer protection is verified, simultaneously, the reliability of an outlet pressure plate for transformer protection is tested, test lose and repetition phenomenon is prevented in the regular inspection work of a transformer protection device, high-efficient and accurate completion of regular inspection tasks is guaranteed, the regular inspection process is more reasonable, the work efficiency is raised, and the regular inspection time for transformer protection is effectively shortened. According to the trip-out matrix test box for transformer protection, the structure is simple, the practicality is strong, and high usage and popularization value is provided.
Description
Technical field
The utility model belongs to the technical field of relay protection check, particularly a kind of tranformer protection tripping operation matrix check box.
Background technology
As everyone knows, power transformer is the visual plant of transformer station, the hinge link of power network is being born important tasks such as the boosting of electrical network, step-down and voltage-regulation, and the safe and stable operation of electric system is had great function and directly affects the deliverability of converting station electric power load.Power transformer is as one of nucleus equipment of electric system, and the length of its power off time directly affects the safe and stable operation of electric system during periodic inspection.In recent years; raising along with Chinese economic development and living standards of the people; the need for electricity amount increases rapidly; improve tranformer protection effectively and examine efficient surely; shortening equipment power off time becomes and improves the power system power supply reliability; promote power supply service quality, increase the important means of effective delivery.But; often adopt multimeter to measure the action situation of each outlet at the tranformer protection of routine tripping operation outlet matrix check, perhaps adopt 7-8 the line lamp monitored the action situation of each outlet to need a plurality of protection personnel to work in coordination; the wiring complexity is in disorder, and test efficiency is lower.
The utility model content
The purpose of this utility model provide a kind of wiring simple, be convenient to observe, do not need manual measurement, tranformer protection tripping operation matrix check box that checkability is high.
A kind of tranformer protection tripping operation matrix check box; comprise the checkbox housing; on the described checkbox housing a plurality of connection terminals are set; be disposed with corresponding supervision pilot lamp on the described connection terminal; one end of described supervision pilot lamp links together by lead; the other end of described supervision pilot lamp is connected with described connection terminal successively by lead
The supervision pilot lamp of the multiple different colours of luminous employing of described supervision pilot lamp.
Tranformer protection tripping operation matrix check box of the present utility model is by arranging a plurality of connection terminals at the checkbox housing; be disposed with the supervision pilot lamp on the described connection terminal; during use; connection terminal is connected with the outlet of transformer successively; in case monitor the luminous words of pilot lamp; transformer outlet tripping operation is described, more convenient.In addition; monitor the supervision pilot lamp of the multiple different colours of luminous employing of pilot lamp; be convenient to monitor the sequencing of tripping operation outlet; the supervision pilot lamp is lighted the export volume that trips when self-holding circuit can monitor the relay protection action; can in time pinpoint the problems and overhaul; shorten the equipment power off time, improved the power system power supply reliability, promoted power supply service quality.The utility model can disposablely be finished all test connections; monitor all tripping operation outlet loops of tranformer protection; it is carried out integral body relatively; checking tranformer protection tripping operation matrix correctness; also checked simultaneously the reliability of tranformer protection outlet pressing plate; prevented that protection equipment for transformer from deciding omission in the inspection work; few inspection; the generation of duplicate test phenomenon; guaranteed that the efficiently and accurately of deciding the inspection task finishes; make and decide the inspection process and rationalize more, improved work efficiency, effectively shortened the time that tranformer protection is examined surely.The utility model is simple in structure, and is practical, has good value for applications.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Embodiment:
As Fig. 1; tranformer protection tripping operation matrix check box of the present utility model; comprise checkbox housing 1; a plurality of connection terminals 2 are set on the described checkbox housing 1; be disposed with corresponding supervision pilot lamp 3 on the described connection terminal 2; one end of described supervision pilot lamp 3 links together by lead, and the other end of described supervision pilot lamp 3 is connected with described connection terminal 2 successively by lead, the supervision pilot lamp of the multiple different colours of luminous employing of described supervision pilot lamp 3.
Tranformer protection tripping operation matrix check box of the present utility model is by arranging a plurality of connection terminals at the checkbox housing; be disposed with the supervision pilot lamp on the described connection terminal; during use; connection terminal is connected with the outlet of transformer successively; in case monitor the luminous words of pilot lamp; transformer outlet tripping operation is described, more convenient.In addition; monitor the supervision pilot lamp of the multiple different colours of luminous employing of pilot lamp; be convenient to monitor the sequencing of tripping operation outlet; the supervision pilot lamp is lighted the export volume that trips when self-holding circuit can monitor the relay protection action; can in time pinpoint the problems and overhaul; shorten the equipment power off time, improved the power system power supply reliability, promoted power supply service quality.The utility model can disposablely be finished all test connections; monitor all tripping operation outlet loops of tranformer protection; it is carried out integral body relatively; checking tranformer protection tripping operation matrix correctness; also checked simultaneously the reliability of tranformer protection outlet pressing plate; prevented that protection equipment for transformer from deciding omission in the inspection work; few inspection; the generation of duplicate test phenomenon; guaranteed that the efficiently and accurately of deciding the inspection task finishes; make and decide the inspection process and rationalize more, improved work efficiency, effectively shortened the time that tranformer protection is examined surely.The utility model is simple in structure, and is practical, has good value for applications.
