Description
Technical field
The present invention relates to a kind of networking connection method for the next secondary device of power network.
Background technology
Primary equipment under power network refers to the equipment such as cable branch box, ring main unit or high voltage load switch, in prior art
The networking of middle primary equipment is directly to be connected with power network, and the other end is connected with load, the load current certain for break-make and mistake
Load current, in some cases the change due to load or line fault reason make moment impact electric current very big, cause these
Equipment is easy to go wrong, and these equipment just investigate object into emphasis during maintenance.As shown in figure 1, primary equipment B one end is straight
Connect and be connected with power network A, the other end to load is load supplying when primary equipment is in "on" position, when primary equipment is in
The power supply to load is interrupted during gate-dividing state, one end that primary equipment is connected with power network A is powered all the time, when primary equipment goes out
Now exception or failure need power network during maintenance to have a power failure, only in the case where primary equipment does not have electricity completely, maintainer's energy
Safety work.A section where grid power blackout means maintenance point there is not electricity all, have a strong impact on the life of people, study, produce and
Business, not only user is by heavy losses, and power department it is similarly subjected to loss.Although this phenomenon is by it is believed that be very just
Normal very objective phenomenon, it is possible to understand that and tolerance, but people be also desirable to this phenomenon try one's best it is few occur, should not expand as far as possible
Power failure range.Considering how to improve the quality of this kind equipment always for this those skilled in the art, to reduce failure reduction
The maintenance of grid power blackout.Although technical staff has made effort, improve constantly the quality of this kind equipment, due to overload electricity
Stream is inevitable, and the working characteristics of this kind equipment determines that the equipment is a kind of easily out of order equipment, it is necessary to often
Maintenance is changed, therefore power failure phenomenon in section is still constantly occurring.
The content of the invention
It is an object of the invention to provide a kind of networking connection method for the next secondary device of power network, the purpose is to make one
Secondary device power network in maintenance can not have a power failure.
This networking connection method for the next secondary device of power network that the present invention is provided is：The next secondary device of power network with
A hand switch is connected between power network, the hand switch is operated under zero load, control the power-off and energization of primary equipment, it is described
Hand switch includes insulator, high voltage supply terminal, high powered terminal, is conductively connected screw rod, the high voltage supply terminal and
High powered terminal fixes in the insulator and separated by a distance, and high voltage supply terminal is connected with power network, high powered terminal
It is connected with primary equipment, insulator is provided with the threaded connection passage matched with high powered number of terminals, the threaded connection is led to
Road connects high voltage supply terminal and high powered terminal, and the screw rod that is conductively connected can make height by the threaded connection passage
Pressure power supply terminal is connected with high powered terminal or mutually disconnected, and then high powered terminal is obtained electric or power-off.
The hand switch also includes insulation blanket stud, and the insulation blanket stud, which is used to be conductively connected, enters screw thread company after screw rod is exited
Connect road and insulation connection is carried out to high voltage supply terminal and high powered terminal.The hand switch also includes insulation tube, and this is exhausted
Edge pipe can be arranged on threaded connection channel end.
The high voltage supply terminal and high powered terminal are one.It is also equipped with the tail end of the threaded connection passage
One end socket that removably insulate, for cleaning and checking threaded connection passage.
When needing hand switch to control each primary equipment in one group respectively, the high voltage supply terminal is one,
The high powered terminal be two and more than.The high voltage supply terminal is L-shaped, there is at least two connecting screw hole above, these
Connecting screw hole threaded connection passage connection corresponding with one respectively.
The inventive method connects a hand switch in the front end of primary equipment, to one in the case of primary equipment separating brake
Secondary device is powered and power operation, after hand switch is powered to primary equipment, and the equipment, which is closed a floodgate, makes load normally run.When
When exception occurs in primary equipment or failure needs maintenance, operation hand switch powers off primary equipment, and primary equipment is in
Electroless state just can be with safety inspection.Because the operation of hand switch is carried out under no-load condition, the characteristic of hand switch is
Very stable, essentially as conductive cable, the probability gone wrong is minimum.When hand switch controls electric network source, primary equipment
Maintenance can be achieved with without electric safety inspection, without grid power blackout, other load loops do as usual operation, will not be by any shadow
Ring.Both the interests of user ensure that or the economic benefit of power supply department is effectively increased.
Hand switch of the present invention passes through conduction due to high voltage supply terminal, high powered terminal being set in the insulator
Connecting screw rod realizes the break-make of the two, its energy livewire work, and operation is very easy.
