Description
Technical field
It the utility model is related to separating brake technical field, more particularly to a kind of high-pressure vacuum breaker and its emergency opening dress
Put.
Background technology
With the extensive use of high-tension circuit, the requirement to its security is also more and more high, and particularly high-voltage switch gear is set
The requirement higher of breaker in standby and control device.
Product should have the ability of on-load emergency opening, and when being in an emergency, manual operation should be able to reliable disjunction.Such as
This no function of fruit, when being in an emergency, be easy to cause the expansion of accident, and it is understood that most of production of in the market
Product are no this structures, though there is manual brake separating mechanism, this structure is mainly used for the adjustment of breaker opening range and over stroke, it is impossible to
Meet the opening velocity requirement of breaker needs, it is impossible to on-load emergency opening.
KYN28A-12 metal armouring middles high-tension switch gear in the process of running, in order to protect its security, is adopted
Interlock protection mechanisms such as " five is anti-" is taken.When major loop, switchgear in itself or control system break down, breaker cannot electricity
During dynamic separating brake, should just carry out manual brake separating processing to it immediately, but the vacuum circuit breaker in KYN28A-12 high-tension switch cabinets be
Under " five is anti-" device protection, manual brake separating is carried out to vacuum circuit breaker and must first release " five is anti-", and releasing " five is anti-" then needs
Will for a period of time, the sprawling that may so cause the accident.Therefore, when system break down, breaker cannot electronic separating brake when,
It in the case of not releasing " five is anti-", can be carried out promptly cut-offfing vacuum circuit breaker with manual brake separating operation device, and can guarantee that reliable
Rated load current is cut-off, improves the reliability of switch, i.e., manual emergency separating brake is carried out to breaker if necessary, cut off immediately
System power supply.But this must just set the equipment mechanism that emergency opening is carried out to vacuum circuit breaker, and KYN28- on switchgear
The former design of 12 grade high-tension switch gears is no, and the exploitation design of the emergency brake-dividing device of high-tension switch cabinet is a urgently to be resolved hurrily
The problem of.
GG-1A is designed for the high-tension switch cabinet for installing oil or vacuum circuit breaker, the operating head peace of oil-break
In cabinet door, the operation of oil-break carries out directly in the shop front, thus the former design of GG-1A high-tension switch cabinets be not required to it is critical
Anxious switching-off device.With the update of electrical equipment, oil-break is tentatively substituted by vacuum circuit breaker, and vacuum is broken
The manual brake separating operation of road device carries out on its body.With user to oil-break in GG-1A high-voltage switch cabinets by
Step is eliminated and vacuum circuit breaker widely uses, and therefore, GG-1A high-tension switch cabinets are high with KYN28A-12 metal armourings middles
Voltage switching station is the same, and the setting of emergency brake-dividing device is required.
Therefore, how a kind of emergency brake-dividing device is provided, to realize emergency opening, be current those skilled in the art urgently
The technical problem of solution.
