Abstract
The invention discloses a portable shielding top copper bar bus cutting machine which comprises a base. A support sliding bar is arranged at the upper part of the base; an electric motor is connected to the support sliding bar slidably; the bottom end of the electric motor is fixedly connected with an isolation drum in which a grinding wheel cutter is arranged; and the electric motor is in transmission connection with the grinding wheel cutter through a telescopic transmission component. The invention has simple structure and convenient use, no many persons are needed for careful cooperation and a cable caliber is not needed manipulating manually in the cutting process, thereby improving the working efficiency, saving the labor cost and the working time, shortening the replacing time of a relay protection device and improving the reliability of a mains supply; meanwhile, the cut surface of a bus is even, thereby avoiding the short circuit caused by the unevenness of the cut surface. In addition, operators do not need to directly use the cable caliber to cut the bus, thereby preventing the operators from electric shock.
Description
Technical field
The present invention relates to the substation relay protection reforming equipment.
Background technology
The protective relaying device of converting station electric power equipment is when withdrawing from; need the little bus of the screen interconnective special use in top is disconnected; traditional method is to utilize giant bow compass to cut off bus; this method is easy to cause the short circuit of bus; cause protective device malfunction or tripping, bring great hidden danger for the safe and stable operation of electrical network.Along with the fast development of China's power system, the integrated automation of transformation stations is transformed and is just carried out corresponding stepping up.Yet old relay-set withdraws from when carrying out the relay protection transformation, needs the little bus of charged exposed operation is cut off.The traditional common method be with the cable clamp after in the middle of two protection screens little bus being cut off, could withdraw from old relay-set, newly shield in place.Shear history needs many people to cooperate meticulously, although the staff is very conscientious, careful, careful since little bus the gap is little, exposed charged at interval, between little bus rod, interlayer is too little, time-consuming, the effort of shear history; Moreover manually-operated is easy to generate deviation, and shearing area is very irregular, is easy to cause little busbar short-circuit; Operating personnel also have Danger Electric shock risk; When new screen is in place, the touching charged little bus in both sides is arranged and causes the danger of short circuit ground connection.
Summary of the invention
The object of the present invention is to provide a kind of portable shielding top copper bar bus cutting machine.
For achieving the above object, portable shielding top copper bar bus cutting machine of the present invention comprises base, base top is provided with support power slide bar, slidely connect motor on the support power slide bar, the motor bottom is fixed with insulating cylinder, be provided with the grinding wheel cutter in the insulating cylinder, motor is in transmission connection by flexible driving member and grinding wheel cutter.
The insulating cylinder bottom is hinged with enclosed box body.
Described base middle part is provided with the pulling force screw rod, and pulling force screw rod one end protuberate basic unit also is provided with nut.
The present invention has following advantage:
1. the present invention is simple in structure, and is easy to use.During cutting copper rod bus, at first by base whole portable shielding top copper bar bus cutting machine being fixed on needs both sides, protective relaying device front and back out of service, across above place, relay-set screen top copper rod bus.Secondly by adjusting the position of motor on support power slide bar, make grinding wheel bit alignment copper rod bus to be cut; Be the rotation of control motor drives grinding wheel cutter at last, flexible simultaneously driving member drive grinding wheel cutter moves down and realizes the cut-out to the copper rod bus.Above-mentioned cutting-off process need not many people cooperate and manually-operated cable clamp meticulously, has improved operating efficiency, has saved labour cost and working time, has shortened the time that protective relaying device is changed, and has improved the reliability of mains supply.The section of bus can not be short-circuited because of section is irregular in good order simultaneously.In addition, because operating personnel no longer need the direct control clamp to remove to cut off bus, therefore also make operating personnel away from Danger Electric shock risk.In a word; succeeding in developing of portable shielding top copper bar bus cutting machine improved the security that disconnects this working link of copper rod bus greatly, simplified workflow; shorten the time that protective relaying device is changed, improved the power supply reliability of operating efficiency and electrical network.
2. the insulating cylinder bottom is hinged with enclosed box body, enclosed box body can be enclosed within on the bus that needs to disconnect before the cutting bus, rotate enclosed box body then, make enclosed box body in insulating cylinder is enclosed in bus to be cut and grinding wheel cutter, just will be closed in the box body at the broken end of metal that cutting produces during bus like this, and prevent from that the broken end of metal from splashing to cause short circuit.
3. the setting of pulling force screw rod and nut, being convenient to utilize pulling force screw rod and support power slide bar that the present invention is fixed on needs on the protective device out of service.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, portable shielding top copper bar bus cutting machine of the present invention, comprise base 1, base 1 top is provided with support power slide bar 2, slidely connect motor 3 on the support power slide bar 2, motor 3 bottoms are fixed with insulating cylinder 4, are provided with grinding wheel cutter 5 in the insulating cylinder 4, and motor 3 is in transmission connection with grinding wheel cutter 5 by flexible driving member 6.Insulating cylinder 4 bottoms are hinged with enclosed box body 7.Base 1 middle part is provided with pulling force screw rod 8, and pulling force screw rod 8 one end protuberate basic units 1 also are provided with nut 9.Wherein, silk outside pulling force screw rod 8 can all be provided with on the whole piece bar, also can be only a side of nut 9 is provided with outside thread.
As shown in Figure 1; during cutting copper rod bus 12; at first the pulling force screw rod 8 by support power slide bar 2 and middle part is fixed on the both sides, front and back that need protective relaying device out of service with base 1 and whole cutting machine, across above place, relay-set 11 screen top copper rod bus 12.Secondly by adjusting the position of motor 3 on support power slide bar 2, make grinding wheel cutter 5 aim at copper rod bus to be cut; Be that control motor 3 drives 5 rotations of grinding wheel cutters at last, the position of flexible simultaneously driving member 6 fine setting grinding wheel cutters 5 moves down it and realizes cut-out to copper rod bus 12.Above-mentioned cutting-off process need not many people cooperate and manually-operated cable clamp meticulously, has improved operating efficiency, has saved labour cost and working time, has shortened the time that protective relaying device is changed, and has improved the reliability of mains supply.The section of bus 12 can not be short-circuited because of section is irregular in good order simultaneously.In addition, because operating personnel no longer need the direct control clamp to remove to cut off bus, therefore also make operating personnel away from Danger Electric shock risk.In a word, succeeding in developing of portable shielding top copper bar bus cutting machine improved the security that disconnects copper rod bus 12 these working links greatly, simplified workflow, shortened the time that protective relaying device is changed, and improves the power supply reliability of electrical network.
