Use this device can effectively avoid the excessive heating of isolating switch galvanic circle parts, within its temperature being controlled to the allowed band of normal operation, thereby reduce repairing frequency of power cut, improve power supply reliability, and having easy to install fast, labour intensity is little, safe and reliable, just with enforcement and simple in structure, the advantage such as economical and practical.
Description
Technical field
The invention belongs to power equipment component technical field, particularly one and keep apart official seal electro-heat equipment.
Background technology
In known technology, the abnormal heating of power equipment is a difficult problem that perplexs for many years work about electric power person.Traditional thermometry is difficult to power equipment low temperature abnormal heating to monitor, particularly outdoor power equipmentGenerate heat more difficult discovery, measurement, thereby easily cause power equipment scaling loss so that jeopardize the safety of power systemOperation. Along with the fast development of China's science and technology, high-precision infrared Using Infrared Technique at electric power isSystem is universal, application, studies meticulously power equipment abnormal heating possibility is provided for our science. According to closely severalThe detection case in year, the abnormal heating of converting equipment changes along with the height of monthly power demand, maximum monthly load,Usual athermic equipment can met generating heat abruptly in month of large load electricity sales amount of kurtosis summer, and 7,8, the converting equipment heating frequency in September (inferior/platform) accounts for 73% annual left and right; In converting equipment, keep apartClose galvanic circle heating and account for the more than 60% of total heat-producing device total degree, heating position is mainly in isolating switchBetween the conduction wire clamp heating at contact and two ends. Although described infrared Using Infrared Technique is to detecting and researchThermal phenomenon provides possibility, but up to now, the excessive heating of avoiding these equipment is not still soughtPreferably solution, is still seriously restricting the normal power supply of peak period and social production, living needsMeet.
Summary of the invention
The invention provides one can effectively solve isolating switch and affect normal power supply because heating temp is too highProblem, and simple in structure, easy for installation, the safe and reliable official seal electro-heat equipment of keeping apart.
Realizing the technical scheme that object of the present invention takes is: this device is by shunting shorting stub and 2～4 pointsStreamline retainer ring composition, the two ends of described shunting shorting stub are provided with and connect cable guide.
Described shunt line retainer ring is pincerlike structure, has the insulation arc support of a pair of mutual fastening, and two is exhaustedOne end of edge arc support is articulated and connected, and the other end touches mutually, two insulation arc supports to touch position equalFor arcuation, between two stands, be provided with back-moving spring and shunt line insulating support plate, the bottom of support is connected with dismountingOperation short handle, this operation short handle is provided with pin.
That makes according to such scheme keeps apart official seal electro-heat equipment, and its beneficial effect is:
1), by the shunting action of shunting shorting stub, can effectively avoid isolating switch galvanic circle partsExcessive heating, within its temperature being controlled to the allowed band of normal operation, produces actual requirement thereby meet,Reduce repairing frequency of power cut, improve power supply reliability.
2) use of this device can adopt status dismounting operation, and the earth potential live working time is short, labour intensityLittle, 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, economical and practical.
Brief description of the drawings

Fig. 2 is the structural representation of shunt line retainer ring in Fig. 1.
Detailed description of the invention
As shown in Figure 1 and Figure 2: the official seal electro-heat equipment of keeping apart of the present invention is by shunting shorting stub 6 and 2～4Individual shunt line retainer ring 4 forms, wherein shunt shorting stub 6 and can adopt copper stranded conductor, its sectional area should meet everyLeave the needs that close maximum load current. The two ends of shunting shorting stub 6 are provided with and connect cable guide 2, for and high pressureThe connection of lead-in wire 3. Shunt line retainer ring 4 is for shunting the fixing of shorting stub 6, to prevent from shunting shorting stub 6Swing under wind-force effect. Shunt line retainer ring 4 adopts pincerlike structure, has the exhausted of a pair of mutual fasteningOne end of edge arc support 7, two insulation arc supports 7 is articulated and connected, and the other end touches mutually. Two insulation arcsThe position that touches of shape support 7 is arc structure, is convenient to descend on the ground push-and-pull to operate its folding, to realizeMiddle contact 5 plug-in mountings of shunt line retainer ring 4 and isolating switch 1 with win. At two insulation arc supports 7Between be provided with back-moving spring 11 and shunt line insulating support plate 8 so that two insulation arc supports 7 close contact,Prevent coming off of shunt line retainer ring 4, avoid shunting contacting of shorting stub 6 and back-moving spring 11. Insulation arcThe lower end of shape support 7 is connected with dismounting operation short handle 9, and is provided with pin 10 on operation short handle 9, forConnection with ground insulating bar (not shown). The upper end of ground insulating bar is sleeve-like configuration,And be provided with the L shaped draw-in groove coordinating with described pin 10, can peg graft and separate with described operation short handle 9 easily.In power supply peak period, can be by the mode that manually adopts status livewire work, by logical the two ends of shunting shorting stub 6Cross and connect on the lead-in wire 3 that cable guide 2 is separately fixed at isolating switch 1, then shunt line retainer ring 4 is plugged onThe top of insulating bar, and upper act is enclosed within shunt line retainer ring 4 successively shunting shorting stub 6 and keeps apartOn the middle contact 5 of pass 1, prevent from shunting disorderly pendulum of shorting stub 6, affect safety. Due to shunting shorting stub 6Shunting action, can effectively avoid the excessive heating of isolating switch galvanic circle parts, by its temperature controlWithin the allowed band of normal operation, produce actual requirement thereby meet, reduce repairing frequency of power cut,Improve power supply reliability.
