Abstract
The utility model discloses a kind of instantaneous reserve protection of electronic type autoreclose breaker, the reserve protection is arranged on the sidepiece of reclosing breaker pedestal (1) and positioned at the rear of reclosing breaker draw bar (2), it includes the split type framework being arranged on pedestal (1), the split type framework includes upper frame body (3) and lower frame body (4), it is rotatablely connected between the framework up and down by bearing pin (5), being set in the framework of lower frame body (4) can electrical conductor, a pair of magnetic adhesive face is formed between upper frame body (3) following side (3 1) and lower frame body upper lateral part (4 2), the connection push rod (6) at the top of upper frame body (3), at the top of push rod (6) bending section (7) is bent to form toward draw bar (2) direction, the suit torque spring (8) in bearing pin (5).When intelligent controller fails, promoting reclosing breaker draw bar by the reserve protection, in order to which electronic breaker provides back-up protection, use is safer so as to realize the trip protection of breaker.
Description
Technical field
Low voltage switch equipment technical field is the utility model is related to, specially a kind of electronic type autoreclose breaker wink
When reserve protection.
Background technology
Reclosing breaker is power supply for three-phase and four-line neutral-point solid ground, electricity system, has overload, short
The function such as road, phase shortage, overvoltage, under-voltage, aftercurrent action protecting, energy protection circuit and electrical equipment are against damages, while
Protection can be provided to earth fault that may be present in circuit and personal mediate contact.At present, this kind of breaker is important is divided into two
Major class, it is divided into mechanically and electronic type, the instantaneous protection of electronic type autoreclose breaker is by intelligent controller by adopting
Collect signal, short-circuit trip avoidance function is finally realized in logic analysis, but the complexity of onsite application environment, controller once damage or by
To interference, so as to lose instantaneous protection.
The content of the invention
The utility model is directed to above weak point, there is provided a kind of instantaneous back-up protection of electronic type autoreclose breaker
Device, when intelligent controller fails, reclosing breaker draw bar is promoted to realize open circuit by the reserve protection
The trip protection of device, in order to which electronic breaker provides back-up protection, use is safer.
Technical scheme is used by the utility model solves its technical problem：The reserve protection is arranged on reclosing
The sidepiece of circuit breaker base and the rear for being located at reclosing breaker draw bar, it includes the split type frame being arranged on pedestal
Body, the split type framework include upper frame body and lower frame body, are rotatablely connected between the framework up and down by bearing pin, in lower frame body
Framework in set can electrical conductor, a pair of magnetic adhesive face is formed between upper frame body following side and lower frame body upper lateral part, upper
Connection push rod at the top of framework, push rod top are bent to form a bending section toward draw bar direction, torque spring are set with bearing pin.
When intelligent controller fails, electrical conductor is powered in framework below lower frame body, by electronic induction in lower frame body
Upper lateral part instantaneously produces strong magnetic, and a pair of magnetic produces magnetic attracting force between adhesive face, due to leading between framework above and below devising
Bearing pin rotation connection is crossed, under electromagnetic force, upper frame body will rotate around bearing pin toward draw bar direction, and now push rod will band
Dynamic bending section rotates, and bending section promotes draw bar, and final draw bar drives its axis of rotation so as to realize the tripping operation of breaker；Lead
After body power-off, electromagnetic force disappears, and under the drive of torque spring, upper frame body resets.
The utility model is devised, and mounting hole is set between lower frame body and reclosing breaker pedestal.
The utility model devises, and the framework of overlap joint busbar through the lower frame body of breaker is interior to be arranged on reclosing breaker
Pedestal.
Brief description of the drawings
Fig. 1 show the schematic diagram of the present utility model on pedestal；
Fig. 2 show structural representation of the present utility model.
Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings：
It is a specific embodiment of the present utility model as shown in Figure 1-2, the reserve protection breaks installed in reclosing
The sidepiece of road device pedestal 1 and the rear for being located at reclosing breaker draw bar 2, it includes the split type frame being arranged on pedestal 1
Body, the split type framework include upper frame body 3 and lower frame body 4, are rotatablely connected between the framework up and down by bearing pin 5, under
Set in the framework of framework 4 can electrical conductor, form a pair of magnetic between the following side 3-1 of upper frame body 3 and lower frame body upper lateral part 4-2
Adhesive face, in the top of upper frame body 3 connection push rod 6, the top of push rod 6 is bent to form a bending section 7 toward the direction of draw bar 2, in bearing pin 5
Interior suit torque spring 8, sets mounting hole 9, the overlap joint busbar of breaker between lower frame body 4 and reclosing breaker pedestal 1
10 pass through the framework of lower frame body 4 is interior to be arranged on reclosing breaker pedestal 1, and overlap joint busbar 10 can be just crossed by lower frame body 4
Inner space, process rationality can be effectively improved, improve efficiency of assembling.
In this example, under electromagnetic force, as shown in figure 1, push rod 6 rotates counterclockwise and drives bending section 7 to promote
Draw bar 2.
Claims (3)
