Background technology
Control and protective switch is a kind of intelligent device for switching that the functions such as circuit breaker, contactor, thermal relay are rolled into one.Be mainly used in the occasion that need to protect motor.Major function has: short-circuit protection, open phase protection, rotation-clogging protection, overcurrent protection, overvoltage/undervoltage protection and earth leakage protective.The structure of this class switch on market mainly comprises following components: major loop contact terminal system, electromagnetism adhesive system, fault trip system, signal acquiring and processing system.The normal break-make of switch is by the adhesive of electromagnet and has discharged.In running, there is fault, the microprocessor instruction that can go out to thread off, electromagnetic trip coil working, mechanism is transformed into dropout position, and the driving lever in mechanism disconnects the contact of electromagnetism pull-in winding and makes its power-off, and electromagnet discharges, and major loop contact terminal is disconnected.The shortcoming of this mechanism is, is issued to major loop disconnects from dropout instruction, and middle link is many, and the time is long.The first,, when there is large current failure, the longer time may produce infringement to load and switch itself; The second, by the release of electromagnet, disconnect the major loop time long, lasting time of arcing phenomenon between contact is also longer, and it is serious that the damage of contact can become.
Utility model content
The purpose of this utility model is to solve fault disjunction mechanism dropout instruction in prior art and is issued to the more problem of major loop disconnection intermediate link, provides the fault disjunction mechanism that a kind of control and protective switch is used to solve the problems referred to above.
To achieve these goals, the technical solution of the utility model is as follows:
The fault disjunction mechanism that a kind of control and protective switch is used, comprise: operate portions and control part, described operate portions is arranged on control part, described control part comprises fixed contact, moving contact and contact guide rod, described moving contact is socketed on contact guide rod, it is peripheral that described fixed contact is arranged on contact guide rod, described operate portions comprises fork, energy-stored spring, master connecting-rod, slave connecting rod and transmission guide rod, described fork is fixedly connected with one end of energy-stored spring, the other end of described energy-stored spring is fixedly connected with one end of slave connecting rod, the other end of described slave connecting rod is fixedly connected with one end of master connecting-rod, the other end of described master connecting-rod is fixedly connected with transmission guide rod.
As preferred version, on described fork, be also provided with contact driving member and the first fastener member.
As preferred version, on described transmission guide rod, be also provided with the second fastener member.
As preferred version, in described operate portions, be also provided with magnetictrip.
The beneficial effects of the utility model are mainly reflected in: successfully that electromagnetism adhesive system and fault trip system is completely independent, work alone, non-interference, when normal operation, fault trip system is in energy storage state, and the break-make of major loop is controlled by electromagnet; When fault occurs, microprocessor provides the snap-in position of dropout instruction Shi, mechanism throws off rapidly, at the effect draft link of energy-stored spring, rapidly to lower swing, major loop is scolded out rapidly.Breaking course is directly rapid, has well protected the contact of load equipment and switch, has improved the performance of switch, has extended the useful life of switch.
Accompanying drawing explanation
Fig. 1 is the structural representation of energy storage state of the present utility model;
Fig. 2 is the structural representation of not energy storage state of the present utility model;
Embodiment
For making that architectural feature of the present utility model and the effect reached are had a better understanding and awareness, in order to preferred embodiment and accompanying drawing, coordinate detailed explanation, be described as follows:
The fault disjunction mechanism that control and protective switch as a kind of in Fig. 1 is used, comprise: operate portions and control part, described operate portions is arranged on control part, described control part comprises fixed contact 10, moving contact 11 and contact guide rod 12, described moving contact 11 is socketed on contact guide rod 12, described fixed contact 10 is arranged on contact guide rod 12 peripheries, described operate portions comprises fork 1, energy-stored spring 2, slave connecting rod 3, master connecting-rod 4 and transmission guide rod 7, described fork 1 is fixedly connected with one end of energy-stored spring 2, the other end of described energy-stored spring 2 is fixedly connected with one end of slave connecting rod 3, the other end of described slave connecting rod 3 is fixedly connected with one end of master connecting-rod 4, the other end of described master connecting-rod 4 is fixedly connected with transmission guide rod 7.
As preferred version, on described fork 1, be also provided with contact driving member 9 and the first fastener member 5.
As preferred version, on described transmission guide rod 7, be also provided with the second fastener member 8.
As preferred version, in described operate portions, be also provided with magnetictrip 6.
The utility model has two states: energy storage state as shown in Figure 1, not energy storage state as shown in Figure 2.
When mechanism is in the state shown in Fig. 2, transmission guide rod 7 is in uppermost position, and not point-blank, energy-stored spring 2 is not compressed for the node of master connecting-rod 4 and slave connecting rod 3, and the hasp of the A position shown in Fig. 2 is normal, B position hasp be in the state of disengagement.
In the actual use of control and protective switch, need Jiang Ben mechanism to be transformed into the energy storage state shown in Fig. 1 from the not energy storage state shown in Fig. 2.When transmission guide rod 7 is to pressing down LAP, master connecting-rod 4 can, along with rotating certain angle, approach on same straight line master connecting-rod 4 and the node of slave connecting rod 3, the compressed certain stroke of energy-stored spring 2.When transmission guide rod 7 presses down after LAP, can be again under the effect of spring force with the hasp of B position shown in second fastener member 8 self-assembling formation Fig. 1.Make mechanism remain on the state shown in Fig. 1.
When mechanism is in the energy storage state shown in Fig. 1, in the major loop of control and protective switch, there is fault, microprocessor sends dropout instruction, and magnetictrip will move, and promotes the first fastener member 5, makes it separated with fork 1.Under the effect of energy-stored spring 2, fork 1 presses down rapidly moving contact 11 and fixed contact 10 is separated.The hasp that transmission guide rod 7 forms with the second fastener member is separated under the promotion of magnetictrip (magnetictrip is to have sequencing when promoting the first fastener member and the second fastener member) also.
When transmission guide rod 7 is upwards drawn to LAP again, master connecting-rod 4 can drive fork 1 to rotate, and it is got back to the position of the first fastener member 5 formation hasps as shown in the A position in Fig. 2.At this moment the not energy storage state shown in Fig. 2 has just been got back to from the trip status shown in Fig. 3 by mechanism.
In sum, it is only preferred embodiment of the present utility model, not be used for limiting the scope that the utility model is implemented, all equalizations of doing according to the shape described in the utility model claim scope, structure, feature and spirit change and modify, and all should be included within the scope of claim of the present utility model.
