Description
Technical field
A kind of switching-off device is the utility model is related to, specifically a kind of emergency cut-off means of high voltage breaker.
Background technology
Control power supply power-fail, and the accident of tripping electromagnet damage easily occur in operation for primary cut-out, cause
Primary cut-out can not carry out normal sub-switching operation, and past emergent solution is to open high-voltage switch cabinet door, operator
Member puts in hand in cabinet by the opening button of primary cut-out, carries out manual emergency sub-switching operation to primary cut-out by force, by
It is too near apart from high voltage in operating personnel, again without the good precautionary measures, it is easy to which operating personnel are damaged.
With advances in technology, many high-voltage boards are all transformed, and have progressively installed emergency brake-dividing device additional, are used now
Emergency brake-dividing device have two kinds：The first is that knob (or operating handle) sets up separately at two with emergency opening button, each time
Knob (or operating handle) will first be transformed into the position for allowing emergency opening to operate by operation, then press emergency opening button,
It could realize that emergency opening operates；Second is that all equipment mechanisms are designed at one into simultaneously one-hand operation, but each time
Rotary setting is stilled need when being operated in the knob of high-voltage cabinet outer side of door, is driven by knob and is arranged at high-voltage cabinet door
The catch bar of inner side is rotated by 90 ° angle, makes the opening button of device catch bar alignment primary cut-out, is then pressed by emergency opening
Button realizes the emergency opening of primary cut-out.
In above two emergency brake-dividing device, problems with is primarily present：
A, the first knob (or operating handle) sets up separately at two with emergency opening button, easily occurs in emergency
Knob (or operating handle) is not transformed into allows emergency opening operating position, just presses emergency opening button, during operation very not
It is convenient；
Although b, second all equipment mechanisms of emergency brake-dividing device are designed at one, and one-hand operation, should
Device is all installed on high-voltage switch cabinet door, and opening button of the cabinet door away from primary cut-out is mostly in more than 350mm, device
It is oversize yielding；
C, when second of emergency brake-dividing device carries out emergency opening operation every time, will 90 ° of angles of rotation forces bar, make device
Emergency opening button could be pressed after catch bar alignment primary cut-out separating brake button, because being rotating device, uses a period of time
Forbidden afterwards because the reasons such as abrasion occur as soon as the catch bar anglec of rotation, catch bar misalignment primary cut-out separating brake button occurs
Phenomenon；
When d, there is the situation of catch bar misalignment primary cut-out separating brake button, it will be unable to realize the outer emergency opening of cabinet,
During such as high-voltage board without " five is anti-" device, it can only just open high-voltage switch cabinet door and be realized by force by the opening button of primary cut-out
Separating brake, opening time was so not only delayed but also had increased the possibility that operating personnel come to harm；
E, there is catch bar misalignment primary cut-out separating brake button, high-tension switch cabinet has " five is anti-" device again when, not only
The outer emergency opening operation of cabinet can not be realized, while can not also realize and open high-voltage switch cabinet door by force by primary cut-out separating brake
The operation of button.Accident is so will be enlarged by, immeasurable loss is brought to enterprise.
