Abstract
The invention belongs to the technical field of power equipment units, in particular discloses an isolating switch heating-preventing device composed of a shunt short jumper and 2-4 shunt wire fixing rings, wherein the two ends of the shunt short jumper are respectively provided with a lead wire clamp. By adopting the device, overheating of parts of a conducting loop of an isolating switch can be effectively avoided, and the temperature thereof is controlled to be within the range of normal operation, thus reducing frequency of power cut for repairing and improving power supply reliability, and the device has the advantages of low labour intensity, safety and reliability, simple structure as well as economy and practicability, and is rapid in mounting, convenient to use, easy to implement.
Description
Technical field
The invention belongs to the power equipment component technical field, particularly a kind of official seal electro-heat equipment of keeping apart.
Background technology
In technique known, the abnormal heating of power equipment is a difficult problem that perplexs work about electric power person for many years.Traditional thermometry is difficult to power equipment low temperature abnormal heating is monitored, the particularly more difficult discovery of outdoor power equipment heating, measurement, thereby cause the power equipment scaling loss easily so that jeopardize the safe operation of electric power system.Along with the fast development of China's science and technology, high-precision infrared non-contact temperature measuring technology is popularized, is used in electric power system, studies the power equipment abnormal heating meticulously for our science possibility is provided.According to detection case in recent years, the abnormal heating of converting equipment along with the moon electricity sales amount, month peak load height and change, usual athermic equipment can met generating heat abruptly in month of big load electricity sales amount of kurtosis summer, and 7,8, the converting equipment heating frequency in September (inferior/platform) accounts for annual about 73%; In converting equipment, the heating of isolating switch galvanic circle accounts for more than 60% of total heat-producing device total degree, and heating position mainly is the middle contact of isolating switch and the drainage wire clamp heating at two ends.Though described infrared non-contact temperature measuring technology provides possibility to detecting and study the heating phenomenon, but up to now, the excessive heating of avoiding these equipment is not still sought solution preferably, still seriously restricting satisfying of the normal power supply of peak period and social production, living needs.
Summary of the invention
The invention provides and a kind ofly can solve isolating switch influences normal power supply because of heating temp is too high problem effectively, and simple in structure, easy for installation, the safe and reliable official seal electro-heat equipment of keeping apart.
Realize that the technical scheme that purpose of the present invention is taked is: this device is made up of shunting shorting stub and 2～4 shunt line retainer rings, and the two ends of described shunting shorting stub are provided with and connect cable guide.
Described shunt line retainer ring is pincerlike structure, insulation arc support with a pair of mutual fastening, one end of two insulation arc supports is articulated and connected, the other end touches mutually, the position that touches of two insulation arc supports is arcuation, be provided with back-moving spring and shunt line insulation supporting plate between the two stands, the bottom of support is connected with dismounting operation short handle, and this operation short handle is provided with pin.
Keep apart the official seal electro-heat equipment according to what such scheme was made, its beneficial effect is:
1) by shunting the shunting action of shorting stub, can avoid the excessive heating of isolating switch galvanic circle parts effectively, its temperature is controlled within the allowed band of normal operation, produce actual requirement thereby satisfy, reduce the repairing frequency of power cut, improve power supply reliability.
2) use of this device can be adopted status dismounting operation, and the earth potential live operating time is short, and labour intensity is little, and is convenient and swift, safe and reliable, low to the requirement of operating personnel's technical quality, just with enforcement.
3) simple in structure, materials are economized, and are economical and practical.

Fig. 2 is the structural representation of shunt line retainer ring among Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2: the official seal electro-heat equipment of keeping apart of the present invention is made up of shunting shorting stub 6 and 2～4 shunt line retainer rings 4, wherein shunts shorting stub 6 and can adopt copper stranded conductor, and its sectional area should meet the needs of isolating switch maximum load current.The two ends of shunting shorting stub 6 are provided with and connect cable guide 2, are used for and being connected of high-voltage connection 3.Shunt line retainer ring 4 is used to shunt the fixing of shorting stub 6, to prevent to shunt the swing of shorting stub 6 under the wind-force effect.Shunt line retainer ring 4 adopts pincerlike structure, and the end with insulation arc support 7, two insulation arc supports 7 of a pair of mutual fastening is articulated and connected, and the other end touches mutually.The positions that touch of two insulation arc supports 7 are arc structure, are convenient to descend on the ground push-and-pull to operate its folding, with middle contact 5 plug-in mountings of realizing shunt line retainer ring 4 and isolating switch 1 with win.Be provided with back-moving spring 11 and shunt line insulation supporting plate 8 between the arc supports 7 in two insulation,, avoid shunting contacting of shorting stub 6 and back-moving spring 11 so that the tight contact of two insulation arc supports 7 prevents coming off of shunt line retainer ring 4.The lower end of insulation arc support 7 is connected with dismounting operation short handle 9, and is provided with pin 10 on operation short handle 9, is used for and being connected of ground insulating bar (not shown).The upper end of ground insulating bar is a sleeve-like configuration, and is provided with the L shaped draw-in groove that cooperates with described pin 10, can peg graft with described operation short handle 9 easily and separate.In the power supply peak period, can be by the mode of artificial employing status live line working, with the two ends of shunting shorting stub 6 by on the lead-in wire 3 that connects cable guide 2 and be separately fixed at isolating switch 1, again shunt line retainer ring 4 is plugged on the top of insulating bar, and upward act is enclosed within shunt line retainer ring 4 on the middle contact 5 of shunting shorting stub 6 and isolating switch 1 successively, prevent to shunt disorderly pendulum of shorting stub 6, influence safety.Because the shunting action of shunting shorting stub 6, can avoid the excessive heating of isolating switch galvanic circle parts effectively, its temperature is controlled within the allowed band of normal operation, produce actual requirement thereby satisfy, reduce the repairing frequency of power cut, improve power supply reliability.
