Description
Technical field
The utility model relates to instrument, is specifically related to a kind of screen and pushes up little bus composite type crossover tool.
Background technology
At present, mostly adopt the little bus in screen top to connect in the transformer station between protection screen, and the little bus in screen top usually to adopt diameter be the copper rod of Φ 6, Φ 8, for protection and automatics provide power supply and secondary voltage, specifically exchanging still, direct current depends on the control power supply.The little bus in screen top is the long-pending lines of shared remittance such as control power supply, signal power source, protection power source, alternating voltage, AC power, generally is placed on the protection screen top, connects with copper rod, aluminium row or cable.The effect of the little bus in screen top is to compile, distribute and transmit electric energy; they are mainly the miscellaneous equipments such as control, protection, cabinet intraoral illumination lamp, heater power supply are provided; little bus whether the stable operation meeting has influence on ac and dc systems, be the most important thing of substation safety operation.
The little bus in screen top adopts whole connection to lay mostly; when protection screen need to be changed in the middle of certain; in order to guarantee its adjacent operational outfit normal operation; the relaying protection personnel need the little bus of cross-over connection; block the adjacent screen of protection screen and push up little bus, the adjacent screen of protection screen to be withdrawed from is pushed up little bus again be communicated with secondary cable.The protection screen top because little bus is laid in; apart from 2.26 meters on ground; belong to during operation that work high above the ground and working space are narrow and small (to only have 30mm with a layer little bus axle center spacing; two-layer little bus spacing only has 60mm up and down); terminal screw all is positioned at the little bus of operation lower end; be difficult to set about when using screwdriver dismounting screw, the hard wire of crimping, the operation dangerous spot is many.Adjacent screen pushes up the little bus bar bridging 10 minutes/root that reaches consuming time of on average working, and the little bus bar bridging time of single face protection screen, it is long that adjacent protection screen pushes up the little bus bar bridging activity duration between 135-231 minutes, and operating efficiency is very low.
The in-depth of building along with new round electric network reconstruction and digitlization, intelligent power network advances, and in recent years, whenever has every year a large amount of comprehensive automations and relay-set cabinet to change transformation, so that the relaying protection personnel are more and more in the face of the screen little bus bar bridging operation in top.How effectively shortening adjacent screen and push up the little bus bar bridging activity duration, improve operational security, is a difficult problem of pendulum in face of the relaying protection professional.
Summary of the invention
The purpose of this utility model is: provide a kind of screen to push up little bus composite type crossover tool, effectively shorten adjacent screen and push up the little bus bar bridging activity duration, improve operational security.
Technical solution of the present utility model is: this composite type crossover tool comprises insulating base, conduction copper rod and little bus pressure nose, establish in the insulating base and press the nose installation cavity, the plug-in type conduction copper rod that is threaded on the insulating base, the bottom of conduction copper rod is stretched into and is pressed in the nose installation cavity, the bottom of conduction copper rod is installed little bus through nut and is pressed nose, expansion slot is installed through nut in the top of conduction copper rod, whole formation composite type crossover tool.
When protection screen need to be changed in the middle of certain; the composite type crossover tool is placed at top at this protection screen; the relaying protection personnel will need the little bus of cross-over connection to be pressed in the little bus pressure nose; the expansion slot connecting lead wire; block adjacent screen and push up little bus, remove again the composite type crossover tool after changing corresponding protection screen.
The advantage of the utility model type is: 1, simple in structure, with low cost, easy to operate, changed the little bus bar bridging work operations pattern in screen top, and reduced labour intensity, shortened interruption duration, reduced the flow process operation, improved operating efficiency; 2, the application of the little bus bar bridging instrument in screen top; reduced the dangerous spot in the secondary work in protection screen new clothes and the Renewal process; reduced the preparation of Work tool; standardized construction; guarantee construction technology and quality; reduce little bus construction hidden danger, for the safe operation of electrical network lays a solid foundation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 insulating base, 2 conduction copper rods, 3 little buses are pressed nose, and 4 press nose installation cavity, 5 expansion slots.
Embodiment
As shown in Figure 1, this composite type crossover tool comprises insulating base 1, conduction copper rod 2 and little bus pressure nose 3, establish in the insulating base 1 and press nose installation cavity 4, on the insulating base 1 plug-in type be threaded the conduction copper rod 2, the bottom of conduction copper rod 2 is stretched into and is pressed in the nose installation cavity 4, the bottom of conduction copper rod 2 is installed little bus through nut and is pressed nose 3, and expansion slot 5 is installed through nut in the top of conduction copper rod 1, and integral body consists of the composite type crossover tool.
When protection screen need to be changed in the middle of certain; the composite type crossover tool is placed at top at this protection screen; the relaying protection personnel will need the little bus of cross-over connection to be pressed in the little bus pressure nose 3; expansion slot 5 connecting lead wires; block adjacent screen and push up little bus, remove again the composite type crossover tool after changing corresponding protection screen.
