Abstract
The utility model discloses a device capable of preventing switch cabinet contacts from being burned and damaged. The device comprises a shell body 2; a static contact 4 is arranged inside the shell body 2; the front end of the static contact 4 is provided with a moving contact 5 matched with the static contact 4; the shell body is provided with a sensor 1; the sensor 1 is connected with a detection system 3 through a wire; the sensor 1 is a temperature sensor 1. According to the device of the utility model, based on an original switch, the sensor 1 is arranged on a position which can emits heat easily, and is connected with the detection system 3 through the wire; when the shell body emits heat abnormally, an abnormal position can be displayed in the face of a worker; as a result, the abnormal position can be found intuitively and effectively, a problem can be solved quickly, and a more serious accident caused by the abnormal position can be prevented; and therefore, major accidents can be effectively prevented, and the reliability of the operation of equipment and a power grid can be greatly improved. The device of the utility model has the advantages of simple structure, convenient usage, effectively improved safety and reliability of an unattended substation, and great application and popularization value.
Description
Technical field
The utility model belongs to the safety practice technical field, is specifically related to a kind of prevention switch cabinet contact scaling loss device.
Background technology
The old-fashioned middle-low voltage switch cabinet of employed GG1A type is replaced by novel XGN cabinet, KYN cabinet in system at present.Newly, old cabinet type Comparatively speaking, therefore GG1A type switch cubicle just progressively is eliminated owing to exist many potential safety hazards can not satisfy the anti-requirement of arranging; And XGN cabinet, KYN cabinet because novel in design, explosive-proof grade is high, the safer plurality of advantages such as more humane of five anti-dependable performances, operation and being widely used in system.Although new cabinet type explosive-proof grade is high, belong to all-sealed structure, but from the another one angle, also there is the problem of a general character in the switch cubicle of this all-sealed structure, this problem is very typical, the a difficult problem that is perplexing equipment safety operation for many years: be not easy in time be found when the temperature anomaly of inside switch cabinet conducting position raises in operational process always, the management mode of especially current this " large collection control ", a lot of stations all are unattended operation transformer stations, when by the time being found often be to equipment because of the serious cause thermal damage of crossing, can't repair and the stage of forced outage.It is very passive that this seems for the operation maintenance of equipment, can't realize in advance precognition and pre-control to equipment operation condition.By investigation and analysis for many years, the main position that causes temperature anomaly rising in the switch cubicle is the contact position at the dynamic and static contact of handcart.Because it is inner just in time to be positioned at the static contact box in operational process during the dynamic and static contact of handcart, insert space is relatively narrow and small, and heat is easy to gather and be difficult for shedding at this, when heat reaches certain degree, will damage insulation, cause the accident, badly influence the safe and stable operation of electrical network.A kind of high voltage switch contact status detector in 201120028915.5 comprises: detect vehicle frame; Several detection contact, distributing installation is on the machine plate, quantity and the position of moving contact are identical on its quantity and distributing position and the high-voltage switch gear dolly, and its shape, size and mutual distance are consistent with the static contact of high-voltage board, form the simulation static contact of one group of simulated high-pressure cabinet static contact.It holds the contact state of high-voltage switch gear by static contact and the contact resistance between the moving contact, spring pressure, contact synchronism that detecting device is convenient for measuring switch with this, in time remove a hidden danger, avoid the generation of high-voltage switch contact heating, over-heated fault, but it is more complicated structurally, it is many to relate to the unit, one is out of order that all just are out of order, and is difficult for the looking up the fault point, so need a kind of device of simple in structure, easy to use, real-time detection.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, the prevention switch cabinet contact scaling loss device of easy to use and Real-Time Monitoring.
Realize that the technical scheme that the purpose of this utility model adopts is: a kind of prevention switch cabinet contact scaling loss device, comprise housing, in the described housing static contact is set, the moving contact that the setting of described static contact front end cooperates with it, on the described housing sensor is set, described sensor links to each other with detection system by wire.
Described sensor is temperature sensing sensor.
The utility model on the basis of original housing at the easy location settings sensor of heating, be connected with detection system by wire, in the time of the housing abnormal heating, will pass through detection system, be presented in face of the staff, the position that so just can intuitively effectively note abnormalities, deal with problems fast, prevent that it from causing accident more, thereby realize in advance precognition and pre-control to equipment operation condition, provide strong foundation for we formulate Strategies of Maintenance, effectively avoided the generation of accident, greatly improved the reliability of equipment and operation of power networks.The utility model is simple in structure, easy to use, Effective Raise the safety and reliability of unattended operation transformer station, have good application value.
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 shown in Figure 1: a kind of prevention switch cabinet contact scaling loss device, comprise housing 2, static contact 4 is set in the described housing, the moving contact 5 that described static contact 4 front end settings cooperate with it, sensor 1 is set on the described housing, and described sensor 1 links to each other with detection system 3 by wire.Described sensor 1 is temperature sensing sensor.The utility model on the basis of original housing at the easy location settings sensor 1 of heating, be connected with detection system 3 by wire, in the time of housing 2 abnormal heating, will pass through detection system 3, be presented in face of the staff, the position that so just can intuitively effectively note abnormalities, deal with problems fast, prevent that it from causing accident more, thereby realize in advance precognition and pre-control to equipment operation condition, provide strong foundation for we formulate Strategies of Maintenance, effectively avoided the generation of accident, greatly improved the reliability of equipment and operation of power networks.The utility model is simple in structure, easy to use, Effective Raise the safety and reliability of unattended operation transformer station, have good application value.
