Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
In the figure 1, the energy-releasing press rod comprises an energy-releasing press rod 1, a lock plate 2, a T-shaped groove 2-1, a bent inclined part 2-11, a micro switch 3, an indication ejector rod 4, a V-shaped groove 4-1, a first riveting shaft 5, an interlocking clamping plate 6, a transverse plate 6-1, a vertical plate 6-2, an acting end 6-3, a spring 7, a second riveting shaft 8 and the like.
As shown in figure 1, the invention is an electric-operated interlocking device, which comprises an interlocking clamping plate 6 which is rotationally arranged, wherein a first riveting shaft 5 is fixed at the end part of a transverse plate 6-1 of the interlocking clamping plate 6, and a second riveting shaft 8 is fixed at the end part of a vertical plate 6-2 of the interlocking clamping plate 6; the vertical plate 6-2 is connected with the locking plate 2 in a matched mode, the second riveting shaft 8 is arranged in a T-shaped groove 2-1 formed in the surface of the lower portion of the locking plate 2, the transverse plate 6-1 is connected with the indication ejector rod 4 in a matched mode, the first riveting shaft 5 is arranged in a V-shaped groove 4-1 formed in the indication ejector rod 4, the energy release pressing rod 1 is arranged at the lower portion of the left side of the locking plate 2, the acting end 6-3 of the interlocking clamping plate 6 is matched with the energy release pressing rod 1, and when the interlocking clamping plate 6 rotates clockwise, the acting end 6-3 pushes the energy release pressing rod 1 to move upwards.
The lower part of the transverse plate 6-1 of the interlocking clamping plate 6 is connected with a spring 7.
The right side of the upper part of the locking plate 2 is provided with a microswitch 3.
The lower part of the T-shaped groove 2-1 is provided with a bent inclined part 2-11, and the side edge of the bent inclined part 2-11 is parallel to the vertical edge of the indicating mandril 4.
The working process of the invention is as follows: the interlocking clamping plate 6 is driven to rotate by indicating the up-and-down movement of the mandril 4 (the movement is provided by the breaker body and is used for indicating the ON/OFF state of the breaker), so that the device can complete the interlocking function.
The state shown in fig. 1 is an OFF state, when the circuit breaker is switched on, the indicating ejector rod 4 is driven to move upwards, the first riveting shaft 5 is inserted into a V-shaped groove 4-1 of the indicating ejector rod, so that the interlocking clamping plate 6 rotates anticlockwise, the second riveting shaft 8 riveted with the interlocking clamping plate 6 moves in a T-shaped groove 2-1 of the locking plate 2, and at the moment, due to the interference effect of the locking plate 2 and the second riveting shaft 8, the locking plate 2 cannot be lifted. The padlock function can be realized by electric operation only in the OFF state.
The state shown in fig. 1 is an OFF state, and when the circuit breaker is switched on, the indicating mandril 4 is driven to move downwards, so that the interlocking clamping plate 6 rotates clockwise, the second riveting shaft 2 interferes with the locking plate 2, and the locking plate 2 cannot be lifted. At the moment, the downward movement stroke of the energy release pressure rod 1 is calculated to ensure that the pressing stroke cannot be blocked, and at the moment, the normal electric operation action and the incapability of lifting the lock plate 2 can be ensured.
When the electric operation is in a 0FF state, the locking plate 2 is lifted upwards, the interlocking clamping plate 6 is driven to rotate clockwise through the bent inclined part 2-11 at the lower half part of the T-shaped groove 2-1 of the locking plate 2, when the locking plate reaches the straight-line position of the T-shaped groove 2-1, the locking plate rotates to the maximum angle, the energy release pressing plate 1 is blocked by the leftmost end of the interlocking clamping plate 6 at the moment and cannot be pressed down, the electric operation is powered off due to the fact that the locking plate 2 moves upwards, the micro switch 3 is pressed down, and at the moment, the electric operation is manual and the electric operation cannot be.
