Abstract
The utility model discloses an interlocking device for the electrical operation of a drawer unit in a power distribution system. The utility model is characterized in that an interlinking dial (3) is added between an electrical operation circuit breaker (1) and an electrical operation mechanism (2) horizontally positioned inside the drawer, the interlinking dial (3) is moved upwards vertically by the horizontal motion of a circuit breaker operation handle, an interlocking rod (4) movable upwards and downwards and withstood by a spring (5) is positioned vertically just downside the dial (3), and the interlocking rod (4) is able to insert into a drawer bottom plate (6) corresponding to the closed state of the switch and the lockhole on the spacing plate (7) of the drawer. The interlocking device has the advantages of simple process, flexible operation, reliability, and ability to meet the interlocking requirement that the drawer unit can not be drawn out when the circuit breaker is closed and enable the safety protection.
Description
Technical field
The utility model relates to the electrically operated interlock of a kind of drawer unit in the electrical power distribution system switchgear.
Background technology
In electric power power transmission and transformation system switchgear, usually electrically operated circuit breaker need be installed in drawer unit.The device that uses is that electrically operated circuit breaker directly is installed in drawer at present, and the drawer unit locking can not be extracted out when this device can't be realized breaker closing, can't realize the requirement of security protection, had great production safety and personal safety hidden danger.
The utility model content
The utility model is to design the electrically operated interlock of a kind of reliable drawer unit.
The technical solution adopted in the utility model is: install an interlock plectrum between the electric operating circuit breaker that level is installed in drawer and its motor-operating mechanism additional, the motion of breaker operator handle horizontal direction can make plectrum move in vertical direction, under plectrum vertical the blocking lever movable up and down that is withstood by spring is installed, blocking lever can penetrate the drawer-bottom board of position correspondence when the switch "on" position and the interlocking hole on the drawer layer dividing plate simultaneously.
The motion of the electrically operated interlock of the drawer unit that the utility model provides breaker closing handle when closing a floodgate rotates plectrum, thereby blocking lever is depressed the location hole that passes on drawer-bottom board and the drawer layer dividing plate, holddown spring can not be extracted drawer out under the switch "on" position simultaneously; When separating brake, the motion of breaker closing handle is upwards rotated plectrum, unclamps blocking lever, and spring will eject location hole on drawer-bottom board and the drawer layer dividing plate to blocking lever, removes interlocking, and drawer can be extracted out.
This interlock manufacture craft is simple, flexible operation, reliable, and the interlock requirement that drawer unit can't be extracted out when having realized breaker closing has reached the purpose of security protection.
Description of drawings
Accompanying drawing is the structural representation of an embodiment of the utility model drawer unit electric operating interlock.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, circuit breaker 2, motor-operating mechanism 3, plectrum 4, blocking lever 5, spring 6, pin drawer-bottom board 7, drawer layer dividing plate
As shown in the figure, install interlock plectrum 3 between the electric operating circuit breaker of in drawer, installing 1 and its motor-operating mechanism 2 additional, the motion of breaker operator handle horizontal direction can make plectrum 3 move in vertical direction, under plectrum 3 vertical the blocking lever movable up and down 4 that is withstood by spring 5 is installed, blocking lever 4 can penetrate the drawer-bottom board 6 of position correspondence when the switch "on" position and the interlocking hole on the drawer layer dividing plate 7 simultaneously.
The motion of the electrically operated interlock of the drawer unit that the utility model provides breaker closing handle when closing a floodgate rotates plectrum 3, thereby blocking lever 4 is depressed the location hole that passes on drawer-bottom board 6 and the drawer layer dividing plate 7, holddown spring 5 can not be extracted drawer out under the switch "on" position simultaneously; When separating brake, the motion of breaker closing handle is upwards rotated plectrum 3, unclamps blocking lever 4, and spring 5 will be removed interlocking to the location hole on blocking lever 4 ejection drawer-bottom boards 6 and the drawer layer dividing plate 7, and drawer can be extracted out.This device manufacture craft is simple, flexible operation, reliable, and the interlock requirement that drawer unit can't be extracted out when having realized breaker closing has reached the purpose of security protection.
Claims (1)
- A kind of drawer unit electric operating interlock, it is characterized in that: add an interlock plectrum (3) between the electric operating circuit breaker (1) that level is installed in the drawer and its motor-operating mechanism (2), the motion of breaker operator handle horizontal direction can make plectrum (3) move in vertical direction, under plectrum (3) vertical the blocking lever movable up and down (4) that is withstood by spring (5) is installed, blocking lever (4) can penetrate the drawer-bottom board (6) of position correspondence when the switch "on" position and the interlocking hole on the drawer layer dividing plate (7) simultaneously.
