" the electrical safety technical data " that TaiWan, China board of workers labourer safety and sanitation research institute published in 1999
It is pointed out in the research report presided over by Su Wenyuan：" one of the main reason for electrification accident is always labourer's unexpected injury, should be as possible
It avoids protecting labourer safe.The main reason for electrification accident occurs is public institution and labourer to the cognition of electrical safety not
Foot, making working site, there are the potential dangers such as unsafe environment and unsafe behavior." common electrical safety disaster master
Will there are two types of, the first is from using electrical mechanical equipment, and second is the carelessness in electric operation.In order to remedy thing
Industry unit and labourer are insufficient to the cognition of electrical safety, prevent from generating harm using electrical operation, " labourer's safety and sanitation are set
Apply rule " in the 45th article, further peremptory norm employer need to have safety devices, that is, right using electrical mechanical equipment
In the machinery for using power running, there is notable danger person, should appropriate location be provided with the emergency braking apparatus of distinguishing mark,
Power is interdicted immediately and is interlocked with braking system, can quickly stop the operating of machinery when urgent.In addition, for preventing using electricity
In terms of the operation of gas generates harm, in power failure operation, " labourer's safety and sanitation facility rule " the 254th article of regulation is employed
It is main for being engaged in the circuit, the circuit support or the laying close to the circuit working substance after open circuit, construction, checking, repair
Reason, paint when operations, the switch of open circuit should be taken in operation with regard to the circuit after open circuit is confirmed, should " locking " or
Indicate the facility of " forbidding power transmission ", " in power failure operation " or setting monitoring personnel monitoring.It is aforementioned the first come from using electrical
Mechanical equipment disaster, caused by the reason is that almost most people for electrical safety blocking principle of dynamics cognition not
Foot.Although the 254th article of " labourer's safety and sanitation facility rule " further provides for, circuit take the switch of open circuit in
" locking " is answered in operation, but up to now, the regulation for being somebody's turn to do " locking " is all often flowed in empty talk, and there is no certain realities
Row.
According to branch switches of the International Power regulation NEC.422.31. (430.102) (440.14) as xegregating unit
Or breaker should have blocking device.Lockable person when being in consuming device visual range or open a way on xegregating unit position.
Its lockout mechanisms should be placed in appropriate location.Its regulation principle and purposes for prevent misdelivery electricity, inverse power transmission (do not influence it is public
In the case of safety！)：
1. private interior distributor cap does not have to locking.
2. public place electricity consumption will lock.
3. switch handle can be used to lock for motor centralized control panel.
4. having unsafe condition after locking must not lock！
Blocking device is prevents misdelivery electricity, inverse power transmission ... etc., because ocular vision has the situation that can't see, it may occur however that and it is dangerous,
So it can just wish to be latched during repair, to ensure safety.In view of this, manufacture in the world the producer of switch all have production it is relevant
Product.It is waited including external hanging type, internal key type ... numerous.Equally in U.S. OSHA, fire service law regulation ... etc., have strong
The regulation and rule of punishing of property processed.
In special place, demand that the requirement for switch has its different again, for example in many hazardous areas, such as change
Factory, powder magazine, gas, liquid factory, military installations ... etc. are learned, it is certain switch to be required to close in power transmission with electric switch
It closes, it is inaccurate accidentally to be touched switch open circuit or malfunctioned, serious loss is caused, for example the stove heart is melting high temperature high pressure liquid,
Ouster le main consequence can be caused, so in certain Code in Hazardous Special Locations, switch must be the state for being latched in energization (closure) ON,
Because of above-mentioned reason, the whole world manufactures the producer of killer switch, on the device of switch locking, also there is a kind of locking
In the device of (closure) the ON states of energization, and manufacture another product.
In Code in Hazardous Special Locations environment, but have certain specific functions be by demand, for example in many computer rooms that nobody garrisons,
Its killer switch is in certain circuits, it is necessary to prevent external force malfunction from causing to power off, and cause damages and accident even occurs.But
Be in the circuit, when an accident occurs, whether overload, fault current, earth fault ... etc., it is necessary to the breaker be allowed to jump
It is de-, in case making equipment that damage occur even causes fire！So in the requirement of above-mentioned blocking device, and different from above two
State, a kind of forced blocking are closed ON states in being powered, and a kind of forced blocking breaks OFF in off-position, and when failure is again necessary
Breaker can be allowed to make the action of escape so that accident is isolated.
It is that two breakers must be made mutually to do the action to lock there are many situation in many cases of practical power systems
State, i.e. two breaker interlocking Interlock, i.e. two breakers wherein only have an energization, it is impossible to and two are powered simultaneously,
It can cause short circuit accident.Above-mentioned state is most of in a general case all to use automatic transfer switch (namely being commonly called as ATS),
But automatic transfer switch is typically all two and comes on same casing, and the necessary same specification of breaker, in practical shape
Under condition, all flexible application modes are lost, if the device that mode improves can be locked with safety lock for switching of the present invention, then may be used
To solve long-term above-mentioned inconvenience.But it is able to accomplish that electrical resistance, to the function of lock, just meets its safety with mechanicalness
It is required that.
Again when three breakers must be done to lock status, i.e., three breakers interlock the function of interlocking Tie, that is, three disconnected
Road device at most only allows two and is closed at ON, if the improvement of present invention switch locking device can be applied, then can solve to grow
The problem of since long.And since machinery can be carried out with electrical aspect to lock, its absolute reliability can be improved.And by
The contact output of state, can be conducive to identification, increase the convenience used and safety.The present invention and also improve, such as
Inconvenience and shortcoming in M318184 Patent Case no-fuse switch locking device patents can only lock the mode of escape position,
Although having met the requirement for the blocking device that must be able to power failure locking during repair, other aforementioned different work(can not be common to
The situation of energy demand., which there are the mode of latching in countries in the world, in the prior art is closed ON, breaks OFF, and different modes needs
There are different lockset and component, derive multiple safety lock embodiment aspect, so by the increase for causing production cost and increase
The puzzlement of burden and owner in the management of product.More than variety of problems exists for a long time, and domestic and international dealer can not properly solve always
Certainly this problems such as, to promote the safety in electrical equipment and operation.
