Abstract
The utility model discloses a circuit breaker friction ground structure for switch equipment in an electric power distribution system. A ground bar (7) of a circuit breaker in the switch equipment is arranged below a centre spacer (1), the centre spacer (1) is provided with a square hole, the ground bar (7) bends locally in a bow shape, the bending part is inserted into the square hole of the centre spacer (1) to form a friction ground part, a spring hold-down mechanism consisting of a shaft (2), a spring (4), a gasket cap (5) and a pin (6) fastens the ground bar (7) on the centre spacer (1), and the spring (4) can support the friction ground part of the ground bar (7) upward from the square hole of the centre spacer (1). The lower part of the ground bar of the circuit breaker friction ground structure is provided with the spring, so the spring ensures that the ground bar is closely connected with the circuit breaker when the circuit breaker is pushed into a compartment and is pressed on the ground bar, thereby realizing the reliable grounding.
Description
Technical field
The utility model relates to a kind of circuit interrupter grounding structure in the electrical power distribution system switchgear.
Background technology
The circuit interrupter grounding structure of a kind of switchgear commonly used in the electric power power transmission and transformation system.The circuit interrupter grounding structure of the switch cubicle that uses mostly is directly to fixedly mount ground connection row on the median septum of switchgear at present.This structure can't realize the tight ground connection of circuit breaker, makes the ground connection of circuit breaker unreliable.
Summary of the invention
The purpose of this utility model is to design the reliable switchgear circuit interrupter grounding of a kind of ground connection structure.
The technical solution adopted in the utility model is: the below that the ground connection row of circuit breaker in the switchgear is installed in median septum, have square hole on the median septum, the arc bending of ground connection composition portion, dogleg section is interted in the median septum square hole and to be constituted the friction grounding part, ground connection row is fastened on the median septum by spring compression mechanism, can be ground connection row's friction grounding part from the square hole of the median septum jack-up that makes progress.
The circuit breaker friction grounding structure of the switchgear that the utility model provides is because spring is arranged at ground connection row bottom, when circuit breaker advance compartment and be pressed in ground connection row when going up spring ground connection row closely is connected with circuit breaker, thereby the realization reliable ground.
Description of drawings
Accompanying drawing is the structural representation of an embodiment of the utility model switchgear circuit breaker friction grounding structure.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, median septum 2, axle 3, nut 4, spring 5, pad cap 6, pin 7, ground connection row
As shown in the figure, the ground connection of circuit breaker row 7 is arranged on the below of median septum 1 in the switchgear, have square hole on the median septum 1, ground connection is arranged 7 local arc bendings, dogleg section is interted in median septum 1 square hole and to be constituted the friction grounding part, by axle 2, spring 4, pad cap 5 with sell the 6 spring compression mechanisms that form and ground connection is arranged 7 be fastened on the median septum 1, spring 4 can be arranged 7 friction grounding part to ground connection from the jack-up that makes progress of the square hole on the median septum 1, and ground connection row 7 is lined with nut 3 between part below the median septum 1 and median septum 1.
The circuit breaker friction grounding structure of the switchgear that the utility model provides is because spring is arranged at ground connection row bottom, when circuit breaker advance compartment and be pressed in ground connection row when going up spring ground connection row closely is connected with circuit breaker, thereby the realization reliable ground.
Claims (2)
1, a kind of circuit breaker friction grounding structure of switchgear, it is characterized in that: ground connection row (7) is arranged on the below of median septum (1), median septum has square hole on (1), ground connection row (7) local arc bending, dogleg section is interted in median septum (1) square hole and to be constituted the friction grounding part, ground connection row (7) is fastened on the median septum (1) by the spring compression mechanism that has axle (2), a spring (4), pad cap (5) and pin (6) to form, and the friction grounding that spring (4) can be arranged ground connection (7) is partly from the square hole of median septum (1) jack-up that makes progress.
