Abstract

The utility model discloses a release auxiliary mechanism, consisting of a support and a relay, on a current leakage circuit breaker. The support and relay are equipped with energy storage and trigger mechanisms with mutually-linked functions. When utilized to switch with a current leakage circuit breaker, the mechanisms, relying on energy storage, can compensate the shortcoming of small force from only release. Working principle of the utility model is as follows: When a circuit breaker with the mechanism is open, a resetting steel needle will store energy into the mechanism instantaneously and simultaneously. When a tripping gear detect current leakage signals and reach the actuating value thereof, the energy in the mechanism will be released to open the circuit breaker; meanwhile, the mechanism stores energy immediately for the next release.

Description

The dropout auxiliary body of residual current circuit breaker

Technical field

The utility model relates to a kind of dropout auxiliary body of residual current circuit breaker electric mechanism, particularly a kind of residual current circuit breaker.

Background technology

Residual current circuit breaker in use, when the appearance that detects the electric leakage situation, it is split by a series of mechanism and closes the action of threading off, but present mechanism's tripping force is little, it is unreliable to use, and can not satisfy the use needs.

Summary of the invention

At the problems referred to above, the purpose of this utility model is to provide the dropout auxiliary body of the good residual current circuit breaker of a kind of result of use.

The technical scheme that the utility model adopted is:

The dropout auxiliary body of residual current circuit breaker, comprise support, the relay that connects the detection of electrical leakage line is installed on the support, relay connects the shake-up flap by driving shaft, the bottom moved end of touching flap connects an end of reset tension spring, the other end of reset tension spring is fixed on the support, on the support of relay one side connecting axle is installed, one frame that resets is installed on the connecting axle by its stroke groove, reset and be connected with extension spring between frame and the support, the front end of frame of resetting has the push rod of resetting, there is the corresponding push pedal that resets that touches flap the rear end, support is equipped with the swing snap close by fulcrum, this pendulum lock has been buckled the revolution resetting means, the top board of swing snap close rear end is corresponding with the shake-up end position on touching flap, the front end of swing snap close has axis, by connecting axle the back link mechanism is installed on the support, one connecting axle is provided with torsion spring, one end of torsion spring is fixed, the other end is connected on the link mechanism of back, this back link mechanism is provided with buckle, the tripping push rod and the catch that resets, buckle is corresponding with the axis position of swing snap close front end, and the catch that resets is arranged on the rear of the push rod that resets.

The beneficial effects of the utility model are: when the switch that cooperates residual current circuit breaker uses, this mechanism utilizes the form of energy storage to remedy and depends merely on the little shortcoming of tripping force, its operation principle is for carrying out energy storage by the draw point that resets that is attached thereto to mechanism when circuit breaker simultaneously the instantaneous of disconnection, the energy of relieving mechanism is opened circuit breaker when release detects electric leakage signal and reaches operating value, mechanism's energy storage is immediately again simultaneously prepared for discharge next time.

Embodiment

With reference to Fig. 1～Fig. 5, the dropout auxiliary body of residual current circuit breaker, comprise support 1, the relay 2 that connects the detection of electrical leakage line is installed on the support 1, relay 2 connects shake-up flap 3 by driving shaft, the bottom moved end of touching flap 3 connects an end of reset tension spring 4, the other end of reset tension spring 4 is fixed on the support 1, on the support 1 of relay 2 one sides connecting axle 10 is installed, 11, one resets frame 5 by its stroke groove 51,52 are installed in connecting axle 10, on 11, reset and be connected with extension spring 6 between frame 5 and the support 1, the front end of frame 5 of resetting has the push rod of resetting 53, there is the corresponding push pedal 54 that resets that touches flap 3 rear end, support 1 is equipped with swing snap close 8 by fulcrum 7, on this swing snap close 8 the revolution resetting means is arranged, the top board 81 of swing snap close 8 rear ends is corresponding with the shake-up end position on touching flap 3, the front end of swing snap close 8 has axis 82, pass through connecting axle 10 on the support 1,11 are equipped with back link mechanism 9, connecting axle 10 is provided with torsion spring 20, one end of torsion spring 20 is fixed, the other end is connected on the link mechanism 9 of back, this back link mechanism 9 is provided with buckle 91, the tripping push rod 92 and the catch 93 that resets, buckle 91 is corresponding with axis 82 positions of swing snap close 8 front ends, and the catch 93 that resets is arranged on the rear of the push rod 53 that resets.In addition, part body can hide by enclosing cover 300.

Revolution resetting means on the described swing snap close 8 comprises torsion spring 83, and this torsion spring 83 is socketed on the fulcrum 7, and the one end is positioned on the axis 82, and the other end is against on the support 1.

With reference to Fig. 5, Fig. 6, this auxiliary body is installed in the residual current circuit breaker and uses, the switch of the catch 93 that resets by reset draw point 200 and residual current circuit breaker on reset push rod 53 and the back link mechanism on the frame that resets of this mechanism is used, and the position of tripping push rod 92 places tripping baffle plate 100 sides of circuit breaker, tripping push rod 92 is used to touch the tripping baffle plate 100 of residual current circuit breaker, when residual current circuit breaker is closed a floodgate closure, this tripping baffle plate 100 is connected to the side of tripping push rod 92, when relay 2 has detected the electric leakage situation, then relay 2 drives and touches flap 3 rotations, the shake-up end that touches flap 3 backs down the top board 81 of swing snap close 8 rear ends, swinging snap close 8 this moment rotates around fulcrum 7, axis 82 breaks away from buckle 91, back link mechanism 9 moves to tripping baffle plate 100 directions under the effect of torsion spring 20, be that tripping baffle plate 100 is realized threading off, residual current circuit breaker disconnects, circuit breaker is instantaneous what disconnect, the draw point 200 that resets moves right under the effect of leakage switch rotation axis, the frame that resets is moved right with the back link mechanism to be resetted, to mechanism's energy storage again, this moment is by the safety switch of operation residual current circuit breaker, the side and making that makes tripping baffle plate 100 the be connected to tripping push rod 92 again draw point 200 that resets breaks away from the catch 93 that resets, this mechanism comes back to closure state, is that the action of a next time is got ready.
