Description
Technical field
This utility model relates to a kind of control and protective switch, belongs to technical field of electric equipment.
Background technology
Control and protective switch be a kind of the functions such as chopper, catalyst, thermorelay are rolled into one intelligent
Device for switching.It is mainly used in the occasion needing that motor is protected.Major function has: short-circuit protection, open-phase protection, stall
Protection, overcurrent protection, overvoltage/undervoltage protection and earth leakage protective.The structure of this kind of switch on market mainly comprises following portion
Point: major loop contact terminal system, electromagnetism adhesive system, fault trip system, signal acquiring and processing system.The normal of switch is led to
Disconnected is by the adhesive of electric magnet and to have discharged.When occurring in that short circuit current in running, instantaneous coil produces
Sufficiently large magnetic field pulls iron core to make mechanism be transformed into trip positions, and the driving lever in mechanism makes the contact of electromagnetism pull-in winding disconnect
Making its power-off, electric magnet discharges, and makes major loop contact terminal disconnect.The shortcoming of this mechanism is to occur to major loop from short circuit current
Disconnecting, middle link is the most, and the time is long.Because short circuit current is very big, longer break will be to touching
Head produces the biggest damage, even causes the adhesion of contact, last contact to separate, causes the accidents such as circuit burnout to send out
Raw.
Utility model content
For above-mentioned the deficiencies in the prior art, this utility model provides a kind of control and guarantor that can quickly separate contact
Protect switch, the instantaneous disjunction mechanism reliable operation of this switch internal, simple in construction, practical, solve in prior art
The problem of the easy adhesion of point, improves safety, decreases loss.
For achieving the above object, the control and protective switch that this utility model uses, including instantaneous disjunction mechanism and housing,
Disjunction mechanism includes static contact and moving contact；Static contact is fixed in housing；Moving contact is fixing with contact guide rod to be connected；Contact is led
It is provided with touch spring between bar bottom and housing bottom；Contact guide rod is hinged with the one end controlling bar；Control the bar other end with
Housing side inwall is hinged；Control bar to be flexibly connected with fork；Control bar to be provided with near between contact side and the crossbeam of housing
Spring；Control bar and be provided above cored；Instantaneous coil it is socketed with on iron core.
Make it is also preferred that the left housing is insulant, be possible to prevent electric leakage, improve security performance.
It is also preferred that the left static contact, moving contact are torus, the contact surface of two contacts is annular, and contact area increases, conduction
Performance is more preferable.
Electromagnetism adhesive system and instantaneous protection system are successfully completely independent and come by this utility model, work alone, mutually
Do not interfere.When circuit is short-circuited electric current time, utilize self energy promote contact, major loop is separated rapidly.Disjunction
Journey is directly rapid, well protects the contact of load equipment and switch, improves the performance of switch, extends the use of switch
Life-span.
Accompanying drawing explanation
Fig. 1 be this utility model electric current less time structural representation.
Fig. 2 be this utility model electric current bigger time structural representation.
Detailed description of the invention
As shown in Figure 1 and Figure 2: control and protective switch, including instantaneous disjunction mechanism and housing 1；Disjunction mechanism includes stationary contact
11 and moving contact 12；Static contact 11 is fixed in housing 1；Moving contact 12 is fixing with contact guide rod 13 to be connected；Contact guide rod 13
It is provided with touch spring 15 between bottom bottom and housing 1；Contact guide rod 13 is hinged with the one end controlling bar 21；Control bar 21 another
One end is hinged with housing 1 side inwall；Control bar 21 to be flexibly connected with fork 22；Control bar 21 near contact side and housing 1
Spring 14 it is provided with between crossbeam；Control bar 21 and be provided above cored 23；Instantaneous coil 231 it is socketed with on iron core 23, instantaneous
Coil 231 will promote iron core 23 to move when electromagnetic field is sufficiently strong, when iron core 23 push lever 21 rotates to an angle,
Control bar 21 and 13 times pressures of band moving contact guide rod can make two contacts separately, swing enough angles when controlling bar 21, control bar 21 He
The hasp of fork 22 will disengage, and fork 22 swings an angle, makes the end of fork 22 push down control bar 21 and makes two contacts protect
Hold the state in disjunction.
It is also preferred that the left housing 1 is made for insulant, to ensure the safety outside housing.
It is also preferred that the left static contact 11, moving contact 12 are torus, the contact surface of two contacts is annular, and contact area increases,
Electric conductivity is more preferable.
When current ratio is less, the disjunction mechanism of control and protective switch is as it is shown in figure 1, flow through on instantaneous coil 231
Electric current is smaller, so the electromagnetic field intensity produced is not enough to promote iron core 23, controls bar 21 under action from the spring 14, the most right
Contact guide rod 13 forms downforce.At this moment deciliter not affected by mechanism of two contacts.
When be short-circuited fault time, the disjunction mechanism of control and protective switch is as in figure 2 it is shown, electric current can be considerably beyond normally
Current value, the powerful electromagnetic field that instantaneous coil 231 produces promotes rapidly iron core 23, controls bar 21 and presses under the promotion of iron core 23
Lower contact guide rod 13 makes dynamic/static contact quickly separate.After commander's bar presses certain stroke 23 times, fork 22 and control bar 21 shape
The hasp become will disengage, and fork 22 swings a low-angle, withstands control bar 21, makes two contacts be maintained at separate state.
Electromagnetism adhesive system and instantaneous protection system are successfully completely independent and come by this utility model, work alone, mutually
Do not interfere.When circuit is short-circuited electric current time, utilize self energy promote contact, major loop is separated rapidly.Disjunction
Journey is directly rapid, well protects the contact of load equipment and switch, improves the performance of switch, extends the use of switch
Life-span.
Preferred embodiment of the present utility model described in detail above.Should be appreciated that the ordinary skill people of this area
Member just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technology neck
In territory, technical staff passes through logical analysis, reasoning or limited reality on the basis of existing technology according to design of the present utility model
Test available technical scheme, all should be in the protection domain being defined in the patent claims.
