Abstract
The utility model discloses a function assisting structure for a five-prevention lock of a high-voltage distribution cabinet. The function assisting structure comprises a padlock (6) on an interlocking plate (5) of a ground switch operating shaft, and is characterized in that a large bent plate (2) is fastened on a right front lateral plate (2) of the high-voltage distribution cabinet, the large bent plate (2) is hinged with a pin shaft (3), the other end of the pin shaft (3) is connected with a small bent plate (4), the small bent plate (4) can rotate left and right along with the pin shaft (3), and the large bent plate (2) and the small bent plate (4) can be mutually matched in a meshed manner. The function assisting structure further enhances the five-prevention function of a switch cabinet, simultaneously prevents unauthorized operators from arbitrary operation, and is simple to manufacture and convenient to use.
Description
Technical field
The utility model relates to the high voltage power distributing cabinet in a kind of electrical power distribution switches equipment, particularly five of high voltage power distributing cabinet anti-lock constructions.
Background technology
In big power station, transformer station and industrial and mining enterprises, widely-used high voltage switchgear is that high voltage power distributing cabinet is accepted and the distribution electric energy.High voltage power distributing cabinet cabinet electrical design requires to have " five is anti-" function, promptly prevents the misoperation circuit breaker, prevents on-load push-and-pull handcart, prevents splice grafting ground, charged pass switch, prevents that earthed switch from sending electricity at earthing position, preventing mistakenly entering charged chamber.Close at circuit breaker, the separating brake process is negligent of control to the position of earthed switch by function for traditional " five is anti-", operating personnel's misoperation phenomenon can occur, and the person is caused damage.
Summary of the invention
The utility model is that the high voltage power distributing cabinet five anti-lock functions of the random operational grounding switch of a kind of personnel of preventing of design are assisted structure.
It is to increase by a cover protector in high voltage power distributing cabinet cabinet earthed switch operating axis position that the utility model high voltage power distributing cabinet five anti-lock functions are assisted structure, comprise the padlock on the earthed switch operating axis interlock plate, it is characterized in that: tighten a big bent plate at the right front side plate of high voltage power distributing cabinet, big bent plate cochain is connected to bearing pin, the bearing pin other end is connected with little bent plate, little bent plate can be with the bearing pin left-right rotation, and big bent plate can cooperate with little bent plate in interlock.
The high voltage power distributing cabinet five anti-lock functions that the utility model provides assist structure when earthed switch is in the diverse location of separating brake, combined floodgate, on earthed switch operating axis interlock plate, hang up padlock, little bent plate has covered the earthed switch handle hole, also prevents to have simultaneously the earthed switch operating axis interlock plate knee-action of padlock.When not changing original high voltage power distribution cabinet, giving " five the is anti-" function of switch cubicle and ensureing on switching manipulation personnel's the safety has increased insurance together again.Install simply, easy to use, do not influence outward appearance.
Description of drawings
Fig. 1 is the main TV structure schematic diagram that the utility model high voltage power distributing cabinet five anti-lock functions are assisted an embodiment assembling of structure;
Fig. 2 is a vertical view embodiment illustrated in fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, right front side plate 2, big bent plate 3, bearing pin 4, little bent plate 5, interlock plate 6, padlock
As shown in the figure, it is to tighten a big bent plate 2 at the right front side plate 1 of high voltage power distributing cabinet that the utility model high voltage power distributing cabinet five anti-lock functions are assisted structure, big bent plate 2 cochains are connected to bearing pin 3, bearing pin 3 other ends are connected with little bent plate 4, little bent plate 4 can be with bearing pin 3 left-right rotation, and big bent plate 2 can cooperate with little bent plate 4 in interlock; On earthed switch operating axis interlock plate 5, padlock 6 is arranged.
When the earthed switch separating brake, earthed switch operation axis hole is covered by bent plate 4, and is installed in padlock 6 lockings on the earthed switch operating axis interlock plate 5, makes operating personnel can not miss splice grafting ground switch; When earthed switch closed a floodgate, earthed switch operating axis interlock plate 5 moved up with the overlapping operation axis hole, and this covering device is the lockable closing position again, prevented personnel's mistake branch ground connection switch.
The utility model high voltage power distributing cabinet five anti-lock functions are assisted structure, have further strengthened switch cubicle five anti-functions, and also stifled simultaneously random operation of having cut off the not operation personnel is made simple, easy to use.
