Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
The specific embodiment of ring main unit of the present utility model, as shown in Figures 1 to 4, ring main unit include setting on cabinet, cabinet
Have and protection device is equipped with the control panel with handle hole, control panel, protection device includes device matrix 1, device base
Body 1 is provided with the perforate 2 that connection is adapted to handle hole, and protecting cover 4 is hinged on the hole wall of perforate 2.Perforate 2 is circular port, protecting cover 4
Shape be adapted to the shape size of perforate 2, during locking in the insertion of protecting cover 4 perforate 2, the wall surface of the hole of now perforate 2 and protecting cover 4
Outer peripheral face laminating contact, limitation protecting cover 4 is excessively absorbed in perforate 2, and the lateral surface of protecting cover is concordant with the front end face of perforate.
Two engaging lugs 42 are interval with along the axial direction of its jointed shaft on protecting cover 4, are all provided with the two engaging lugs 42
There is a hinge hole, the jointed shaft of protecting cover 4 from the hinge hole of two engaging lugs 42 through rear two ends is fixedly connected on device matrix 1
On, on the suit jointed shaft of torsion spring 3 and between two engaging lugs 42, such setting structure is compact, makes the volume of protection device
Reduce.The back side of protecting cover 4 is provided with lock 41, and lock 41 has the jack that a head for locking bar 6 is inserted.For protecting cover to be locked
Only include electromagnet 5 and locking bar 6 in the lockable mechanism of locked position of coupler, electromagnet 5 is arranged at the one of the perforate 2 of device matrix 1
Side, locking bar 6 is connected with the dynamic iron core of electromagnet 5, and driving locking bar 6, which stretches out, when electromagnet 5 is powered is inserted into the jack of lock 41, prevents
Only protecting cover 4 is opened, and electromagnet can also drive locking bar to depart from acting the jack for making it from lock backward, and now protecting cover 4 is with regard to energy
It is enough to be flicked under the elastic force of torsion spring 3, open perforate.The head of locking bar is flat head 61, so makes locking bar be easier to be inserted into
In the jack of lock.
In the electromagnet and ring main unit of the protection device of ring main unit control circuit connection, only ring main unit be in without
Electromagnet can just drive locking bar to be exited from the jack of lock during electricity condition, and perforate is opened, and just can now enter from perforate
Enter and operated into handle hole；When ring main unit is in charging operation state, the head of locking bar is inserted in the jack of lockhole all the time
In, protecting cover is maintained at locked position of coupler, the perforate now connected with handle hole is closed, it is impossible to by operating hole operation ring main unit,
Avoid and security incident is caused to ring main unit live operation, because protecting cover is embedded into perforate, between protecting cover and the end face of perforate
Gap would not be left, so just protecting cover can not by force be opened in locked position of coupler, improve the safety coefficient of ring main unit.
In above-described embodiment of the present utility model, lockable mechanism is acted using solenoid actuated locking bar, simple in construction, into
This is relatively low, in other embodiments, can also set a stepper motor, while by pinion and rack by stepper motor
The translation of rack is converted into drive locking bar to act, or stepper motor can also be changed using nut screw mechanism
Rotation；The head of locking bar can also be set to wedge-shaped head or conical head so that locking bar is inserted into the jack of lock
In.
The embodiment of ring main unit protection device of the present utility model, the ring main unit protection device and above-mentioned ring main unit
Embodiment in protection device structure it is identical, repeat no more.
