Description
Technical field
The utility model relates to a kind of technical field of power system device, specifically a kind of miniaturization 252kV potting breaker of adapted spring mechanism.
Background technology
252 potting breakers are used for the 220kV electrical network; Cut-off and close zygonema road load current and short circuit current; Safety when carrying out contact, switching, route protection, control, measurement, system's adjusting and the circuit and the overhaul of the equipments of power circuit is isolated, and therefore in electric power system, is widely used.The reliability of power equipment, economy and the influence of environment become the problem that Utilities Electric Co. and industrial cousumer are concerned about very much.Increase-volume, apparatus upgrading, old transformation of standing for transformer station can be through the floor space that reduces equipment, height, the novel miniaturization switchgear of employing and the SF of building
6The minimizing of gas use amount realizes; To satisfy high reliability, economy and to reduce purpose to the influence of environment; And the floor space of 252 present potting breakers and whole height etc. can not satisfy requirements such as transformer station's increase-volume, upgrading or old station transformation, and because there is the deficiency in the design in layout structure; Cause center of gravity high, shock resistance is poor.
Summary of the invention
The utility model provides a kind of compact conformation in order to overcome above-mentioned defective, and floor space is little, and center of gravity is low, shock resistance is strong, the miniaturization 252kV potting breaker of the adapted spring mechanism that transmission is reliable and stable.
The technical scheme that the utility model adopts is: a kind of miniaturization 252kV potting breaker of adapted spring mechanism; Comprise bracing frame, sleeve pipe, arc control device, operating mechanism and transmission case, operating mechanism is connected with arc control device through transmission case, and the bracing frame top is provided with a tank body; Arc control device are arranged in this tank body; The tank body top is symmetrical set two sleeve pipes, and inside pipe casing stretches in the tank body through the plug-in type contact and is connected with arc control device, and current transformer is arranged between sleeve pipe and the tank body; At the vertical bindiny mechanism of the side case of tank body, transmission case and operating mechanism are arranged in this mechanism case, and described operating mechanism is a spring operating mechanism, and transmission case is arranged on the top of spring operating mechanism, and transmission case is connected with arc control device.
The lower end of the outer connecting lever of described spring operating mechanism and transmission case is articulated and connected, and the other end of this outer connecting lever is connected with the interior connecting lever of transmission case through splined shaft, and the other end of this interior connecting lever stretches out transmission case and is connected with the insulated tension pole of arc control device.
The utility model is installed in pack into tank body and adopt socket connection with sleeve pipe of arc control device in the same mechanism case with spring operating mechanism and transmission case then, and mechanism case is closely set in a side of tank body; This compact layout and structure; Floor space is little, and center of gravity is low, and shock resistance is strong; The inside and outside connecting lever of spring operating mechanism through transmission case drives cut-offfing and closes and closing action of arc control device, and the simplification drive mechanism makes transmission more reliable and more stable.
Description of drawings
Fig. 1 is the sketch map of the utility model.
Embodiment
Combine accompanying drawing that the utility model is further described at present; Fig. 1 is a kind of embodiment of the utility model, comprises bracing frame 5, sleeve pipe 1, arc control device 4, operating mechanism 7 and transmission case 9 etc., and operating mechanism 7 is connected with arc control device 4 through transmission case 9; Bracing frame 5 tops are provided with a tank body 3; Arc control device 4 are arranged in this tank body 3, and tank body 3 tops are symmetrical set two sleeve pipes 1, and sleeve pipe 1 inside is stretched in the tank body 3 through the plug-in type contact and is connected with arc control device 4; Current transformer 2 is arranged between sleeve pipe 1 and the tank body 3, and current transformer 2 is built-in current transformer 2 usually.At the vertical bindiny mechanism of the side case 8 of tank body 3, promptly mechanism case 8 is for being close to a side that is arranged on tank body 3.Transmission case 9 is arranged in this mechanism case 8 with operating mechanism 7, and described operating mechanism 7 is a spring operating mechanism, and transmission case 9 is arranged on the top of spring operating mechanism, and transmission case 9 is connected with arc control device 4.The lower end of the outer connecting lever of spring operating mechanism in the present embodiment and transmission case 9 is articulated and connected, and the other end of this outer connecting lever is connected with the interior connecting lever of transmission case 9 through splined shaft, and the other end of this interior connecting lever stretches out transmission case 9 and is connected with the insulated tension pole of arc control device 4.The utility model also can be operated three-phase operating mechanism 7 through electrical interlock simultaneously, thereby realizes cut-offfing, closing and close action of three synchronised completion circuit breaker.
The utility model is with pack into tank body 3 and adopt socket connection with sleeve pipe 1 of arc control device 4; Then spring operating mechanism and transmission case 9 are installed in the same mechanism case 8; And mechanism case 8 is closely set in a side of tank body 3; When certain phase spring operating mechanism of operation; Connecting lever moved up and down in the output shaft of spring operating mechanism drove through vertical pull bar and outer connecting lever, simultaneously in connecting lever insulated tension poles of driving corresponding certain phase arc control device 4 inside do upper and lower motion, thereby realize that every phase arc control device 4 moving cells accomplish cut-offfing, closing and close action of circuit breaker separately.This compact layout and structure, floor space is little, and center of gravity is low, and shock resistance is strong, simplifies drive mechanism, makes transmission more reliable and more stable.
Characteristics such as the utlity model has compact conformation, floor space is little, and center of gravity is low, shock resistance is strong, and transmission is reliable and stable.
