TWM370173U - Push-type cut-off safety lock for circuit maintenance and repair of no-fuse breaker - Google Patents

Description

M370173 V. New description: [New technical field] The fuseless circuit breaker circuit maintenance push-type power-off safety lock. Ensure personnel equipment is safe. [Prior Art] Manufacturing technology for the production of solute-free circuit breakers.

[New content] The solute-free circuit breaker circuit repairs the push-type power-off safety lock. The original manufacturer's r-free fuse circuit breaker is installed on the fuseless circuit breaker body cover. The r circuit maintenance push-type power-off safety surface is prevented. When the r-free fuse circuit breaker is opened, the maintenance circuit is repaired. It was accidentally opened by other miscellaneous personnel without permission or the salt-electricity accident of the equipment occurred. [Embodiment] The "Fuseless Circuit Breaker" causes the maintenance of the maintenance circuit-type power-off safety lock of the non-fuse circuit breaker. On the ** wireless line breaker body cover as shown (Figure υ description #1) installation circuit maintenance push-type power failure safety lock as shown (circle 1) description #3 and #4" make no dazzle line breaker After the normal installation is completed, the operation is not shown on the front side (Fig. 2); when the maintenance of the power failure circuit is performed, after the power supply is stabilized, the r circuit repair pushes the power failure safety pin to make 3 M370173 『 push type The power-off safety lock device is shown in the figure (Fig. 3). #4 j Jam the "Fuse-free circuit breaker common trip and power-off device as shown in the figure (Fig. 1) Description #5" and remove the "circuit maintenance push-off" The key of the electric safety lock is shown in the figure (Fig. 1). Description #2』Lock the circuit to make the non-fuse circuit breaker in the open circuit lock state, in case the non-electrician can start the fuseless circuit breaker freely, causing the electric accident. Occurs to ensure the safety of electricity.

Claims (1)

M370173 Sixth, the scope of application for patents·· 1. A fuseless circuit breaker circuit maintenance push-type power-off safety lock, the fuse-free circuit breaker includes the upper cover, the outer casing and the tripping mechanism; the tripping mechanism further comprises: an operating handle The operating handle has a through hole for being rotatably coupled to the fixed shaft of the outer casing to operate the opening (OFF) and the conducting (ON) of the non-fuse circuit breaker; a support seat 'the support seat is rotatably sleeved On a fixed shaft fixed to the outer casing; φ a movable contact, the upper end of the movable contact 舆 is supported on the fixed shaft of the outer casing; a tripping lever, that is, a fuseless circuit breaker Commonly tripping and de-energizing device, one end of the trip bar is movably connected to the return rod, and the other end is slidably connected in the guiding groove of the outer casing; an over-current protection bimetal; the bimetal is fixed on the conductor of the outer casing, The adjusting screw is used to adjust the protection of the overcurrent, and the common tripping and disconnecting electrical device is set to 'to achieve the electrical protection function; * A fixed moving contact, the fixed contact is fixed on the outer casing for making The introduction of power supply; a fuseless circuit breaker circuit maintenance push-type power-off safety lock, using a round mechanical bolt-type fixed lock, connected to the upper cover of the fuseless circuit breaker, and connected with a push-type power-off safety lock device The tripping lever is used to control the tripping sample by driving the safety lock to open or lock the key to drive the power-off safety device. 5 M370173 2·If the circuit maintenance push-type power-off safety town mentioned in the first paragraph of the patent application scope is completed, after the normal use of the fuse-free circuit breaker is completed, it is placed on the front operation panel of the fuseless circuit breaker; When the electrical circuit is repaired, the circuit is repaired and the push-type power-off safety lock is locked after the power is cut off, so that the push-type power-off safety lock device is stuck with the common fuse-breaking device of the fuse-free circuit breaker; and the circuit maintenance push-off is removed. The key of the electric safety lock determines that the circuit puts the non-fuse circuit breaker in the locked state (OFF) to prevent non-electrical personnel from arbitrarily starting the no-fuse circuit breaker, causing electrical accidents to occur and ensuring personnel safety. 3. If the circuit maintenance push type electric safety lock mentioned in the first paragraph of the patent application scope is used, the power-off safety lock is used to drive the power-off safety lock to drive the push-type power-off safety lock device to lock or open the fuseless circuit breaker. Common flea power-off device to achieve the operation or locking function of the fuseless circuit breaker.
