Abstract
The utility model discloses a connection structure of a solid sealed pole and a transmission mechanism of an indoor high voltage vacuum circuit breaker. A bracket connection head (2) is fixed on the solid sealed pole (1). A nylon guide sleeve (3) runs into the bracket connection head (2). The solid sealed pole (1) and the nylon guide sleeve (3) are fixed on a circuit breaker frame (6). One end of an end joint bearing connection rod (5) is connected with the bracket connection head (2) through a positioning pin (4), and the other end is connected with the circuit breaker transmission mechanism (8) through a nut. Through the nylon guide sleeve (3) and the end joint bearing connection rod (5) of the connection structure, a force applied by the transmission mechanism (8) on the solid sealed pole (1) is always consistent with closing and opening directions. The transmission efficiency of the transmission mechanism (8) is greatly improved, and superior mechanical properties of the circuit breaker are ensured.
Description
Technical field
The utility model relates to the indoor high-voltage vacuum circuit breaker in a kind of electrical power distribution system, special relevant with the syndeton of transmission mechanism with the pole of indoor high-voltage vacuum circuit breaker.
Background technology
In existing domestic electrical power distribution system, the transmission mechanism of indoor high-voltage vacuum circuit breaker is fixed in circuit breaker frame by rotational pin, and pole is connected with transmission mechanism by a connecting rod.Because transmission mechanism is around rotational pin motion, so the curve movement of one end of being connected with connecting rod of transmission mechanism is a camber line.It is not always along the direction of closing a floodgate with separating brake that this syndeton makes the direction of the power of transmission mechanism output action on pole, and this just greatly reduces the transmission efficiency of transmission mechanism, and is prone to closing rebound.The quality of the technical parameters such as the splitting or integrating lock speed of circuit breaker and spring has directly determined the quality of circuit breaker performance.Therefore this structure can the serious transmission efficiency that reduces mechanism.
Utility model content
The utility model is for current indoor high-voltage vacuum breaker solid sealed pole and transmission mechanism syndeton is unreasonable causes the problem that transmission efficiency is low, provide a kind of easy to connect, quick, flexible, without clamping stagnation, syndeton that transmission efficiency is high.
The technical solution of the utility model is: the syndeton of a kind of indoor high-voltage vacuum breaker solid sealed pole and transmission mechanism, be characterised in that, on pole, be fixed with a bracket connector, nylon guide penetrates in bracket connector to cover, pole and nylon fairlead are fixed in circuit breaker frame, have an end oscillating bearing connecting rod, its one end is connected with bracket connector by alignment pin, and the other end is connected with driving gear of breaker by nut.
The indoor high-voltage vacuum breaker solid sealed pole that the utility model provides and the syndeton of transmission mechanism, nylon fairlead and end oscillating bearing connecting rod make transmission mechanism act on power on pole keep always with combined floodgate, separating brake direction always, thereby greatly improved the transmission efficiency of transmission mechanism.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the syndeton of existing indoor high-voltage vacuum breaker solid sealed pole and transmission mechanism;
Fig. 2 is the schematic diagram of the syndeton of pole and transmission mechanism for the utility model indoor high-voltage vacuum circuit breaker.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In figure: 1, pole 2, bracket connector 3, nylon fairlead 4, alignment pin 5, end oscillating bearing connecting rod 6, framework 7, rotational pin 8, transmission mechanism 9, connecting rod.
As shown in Figure 2, the syndeton of the utility model indoor high-voltage vacuum breaker solid sealed pole and transmission mechanism is on pole 1, to fix a bracket connector 2, nylon fairlead 3 penetrates in bracket connector 2, pole 1 and nylon fairlead 3 are fixed in circuit breaker frame 6, there is one end oscillating bearing connecting rod 5, its one end is connected with bracket connector 2 by alignment pin 4, and the other end is connected with driving gear of breaker 8 by nut.
It is not that straight line is connected that this syndeton makes between pole 1 and driving gear of breaker 8, but guarantee with nylon fairlead 3 straight-line trajectory that pole 1 inner part moves, with end oscillating bearing connecting rod 5, carry out the component of corrective action other direction on pole 1, thereby guaranteed the mechanical performance that circuit breaker is superior.
