Abstract
The utility model discloses a kind of power switch cabinet electric ground switch interlock.It is that two fanning strips (4,11) are housed on operating axis (3), and instruction baffle plate (1) is in switch cabinet vertical pole (10) inner side, and can slide up and down, back-moving spring (9) one end hangs on switch cabinet vertical pole (10), and one end hangs in instruction baffle plate (1).This electric ground switch interlock parts are few, and structure is simple, easy for installation, and reliability is strong, applied widely, meets the fail safe of electric ground switch interlocked operation, reliability and versatility requirement.
Description
Technical field
The utility model relates to the earthed switch in a kind of power switch cabinet, special relevant with the interlock of earthed switch.
Background technology
Electric ground switch in power switch cabinet is the critical elements of safety ground in high-voltage electrical equipment, and electric ground switch interlock plays instruction earthed switch state, prevents the important function of misoperation.Existing motor switch interlock, fanning strip one operating axis is equipped with, fanning strip one pushes down the elongated hole connecting plate that roller is housed, power transmission shaft riveting has two little connecting levers, be connected with connecting plate respectively, one of them connecting plate is connected with elongated hole connecting plate, and another connecting plate is connected with instruction baffle plate, back-moving spring one end hangs on switch cabinet vertical pole, and one end hangs on instruction baffle plate.When electric ground switch closes a floodgate, operating axis turns clockwise, and fanning strip is synchronous with operating axis, and pushing rolling wheels makes elongated hole connecting plate, connecting plate moves downward, and drive axis promotes instruction baffle plate and moves downward.During electric ground switch separating brake, operating axis is rotated counterclockwise, fanning strip one and operating axis synchronous rotary, and fanning strip one, to away from the motion of roller direction, indicates baffle plate to move upward under action of reset spring.Achieve instruction earthed switch state with the position of instruction baffle plate, prevent the effect of misoperation.This electric ground switch interlock parts are many, complex structure, poor reliability.
Utility model content
The purpose of this utility model is a kind of simple, reliable electric ground switch interlock of design.
The technical solution of the utility model is: a kind of electric ground switch interlock, comprise operating axis, fanning strip one, back-moving spring, instruction baffle plate, switch cabinet vertical pole, it is characterized in that: also comprise a fanning strip 2 11, fanning strip one, fanning strip two are contained on operating axis, instruction baffle plate is inside switch cabinet vertical pole, can slide up and down, back-moving spring one end hangs on switch cabinet vertical pole, and one end hangs on instruction baffle plate.
When electric ground switch closes a floodgate, operating axis turns clockwise, fanning strip one, fanning strip two and operating axis synchronous rotary, and fanning strip one first promotes instruction baffle plate and moves downward, and fanning strip two is pushed down instruction baffle plate again and moved downward.During electric ground switch separating brake, operating axis is rotated counterclockwise, fanning strip one, fanning strip two and operating axis synchronous rotary, and fanning strip one, fanning strip two, to away from the motion of instruction baffle plate direction, indicate baffle plate to move upward under action of reset spring.
The electric ground switch interlock that the utility model provides, on former electric ground switch interlocking basis, decrease roller, elongated hole connecting plate, power transmission shaft, little connecting lever, connecting plate, add a fanning strip and only use two fanning strips, just can realize electric ground switch interlock instruction earthed switch state, prevent the function of misoperation.Parts are few, and structure is simple, easy for installation, and reliability is strong, applied widely, meets the fail safe of electric ground switch interlocked operation, reliability and versatility requirement.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of existing electric ground switch interlock;
Fig. 2 the utility model electric ground switch interlock schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In figure: 1, indicate baffle plate 2, roller 3, operating axis 4, fanning strip 1, elongated hole connecting plate 6, connecting plate 7, little connecting lever 8, power transmission shaft 9, back-moving spring 10, switch cabinet vertical pole 11, fanning strip two.
As shown in Figure 2, the utility model electric ground switch interlock, comprise operating axis 3, fanning strip 1, back-moving spring 9, instruction baffle plate 1, switch cabinet vertical pole 10, it is characterized in that: also comprise a fanning strip 2 11, fanning strip 1 and fanning strip 2 11 are contained on operating axis 3, and instruction baffle plate 1, inside switch cabinet vertical pole 10, can slide up and down, back-moving spring 9 one end hangs on switch cabinet vertical pole 10, and one end hangs on instruction baffle plate 1.
When electric ground switch closes a floodgate, operating axis 3 turns clockwise, fanning strip 1, fanning strip 2 11 and operating axis 3 synchronous rotary, and fanning strip 1 first promotes instruction baffle plate 1 and moves downward, and fanning strip 2 11 is pushed down instruction baffle plate 1 again and moved downward.During electric ground switch separating brake, operating axis 3 is rotated counterclockwise, fanning strip 1, fanning strip 2 11 and operating axis 3 synchronous rotary, fanning strip 1, fanning strip 2 11 move to away from instruction baffle plate 1 direction, instruction baffle plate 1 moves upward under back-moving spring 9 acts on, and realizes electric ground switch interlock instruction earthed switch state, prevents the function of misoperation.
This electric ground switch interlock parts are few, and structure is simple, easy for installation, and reliability is strong, applied widely, meets the fail safe of electric ground switch interlocked operation, reliability and versatility requirement.
