Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
To solve the problems, such as secondary power failure, with reference to powered work operations relevant knowledge, at low-voltage circuit, equipment fault
Reason mode, the utility model innovation development used low voltage failure do not have a power failure processing shunting device, realize it is powered in the case of tear open
Except temporary cable, power off time and power failure area are further reduced.
The processing shunting device as shown in figure 1, a kind of low voltage failure does not have a power failure, including first switch 1, temporary cable 2, second
Switch 3, bus drainage folder 4 and powered no current plug-in and pull-off device 5, the first switch 1 connect bus respectively by three-phase conducting wire
Drainage folder 4, the second switch 3 connects powered no current plug-in and pull-off device 5, the He of first switch 1 by three-phase conducting wire respectively
The second switch 3 is connected by temporary cable 2., can by the device from transformer to distribution box or corridor pickup
Using the switch in place, so as to which failure cable is substituted, resident's uninterrupted operation is realized.Using two switch purposes be exactly
In the case of switching off, either end is set to have voltage but no current when being operated, in practical application, it is possible to use
One switch, temporary cable 2 can be directly connected to, or be connected using terminal box.
As shown in Fig. 2 bus drainage folder 4 is variable caliber type fixture, 4 jaws sides of bus drainage folder are provided with mobilizable
Clamping plate 6, consider current-carrying capacity, price and manufacture craft, we select aluminum material, and intensity is larger, are easy to processing to weld.Altogether
Three single-phase bus drainage folders 4 are made, respectively as A, B, C three-phase.Jaws area is big, possesses stronger bearing capacity, jaws
Side is movable, because busbar variable thickness, is easy to the busbar of the various thickness of firmly clamping, is not easy to come off.
As shown in Figures 3 to 5, the powered no current plug-in and pull-off device 5 includes base 12 and plug 8, the plug 8 and bottom
Seat 12 is connected by buckle structure.The buckle structure includes being located at more than one raised the 9 of the front end of plug 8 and is located at base
With raised 9 corresponding breach 14 in 12 jacks, when plug 8 is connected with base 12, the projection 9 of plug 8 is aligned and is embedded in bottom
In breach 14 in 12 jacks of seat, then rotary connector 8 causes projection 9 and breach 14 to misplace, and realizes the lock of plug 8 and base 12
Tightly.
The plug 8 is provided with flexible sheath 10, and flexible sheath 10 acts in the case where being acted on without external force in elastic component
Under forward extend out, plug 8 is wrapped up wherein, to play a part of protection.
Powered no current plug-in and pull-off device 5 is chosen the copper material processing and fabricating with stronger current-carrying capacity and completed, and base 12 is logical
Cross connecting screw to be installed on air switch, rotary connector 8 can be plugged easily, facilitate staff to operate.
In the case that cable breaks down, using the device by temporary cable 2 be connected to hidden danger cable air switch and
Busbar both sides, it is temporarily isolating trouble point and is handled.After the completion of cable fault reparation, without having a power failure, you can easily remove and face
When cable 2, connection hidden failure point both sides, change to have a power failure and remove the pattern of switch, avoid secondary power failure, reduce residence
People's the rate of complaints.After the completion of cable fault reparation, by nuclear phase, after ensureing that phase sequence is correct, disconnect low voltage failure and do not have a power failure processing
The switch of shunting device, recovers former cable power supply, bus drainage folder 4 and no current plug-in and pull-off device 5 is then removed, when avoiding long
Between have a power failure.
The utility model generates good economic benefit and social benefit：
Economic benefit：After the utility model shunting device comes into operation, powered dismounting temporary cable is realized, device is tried out
Cable fault occurs altogether for 6 middle of the month 26 times afterwards, and the saving fault outage time amounts to 65 hours.Total 300 yuan of outsourcing operating expenses/
Hour, two people are at least needed, working time disbursement is ten thousand yuan of 65*2*300=3.9, if loss of outage 11000 on an hourly basis
First (circuit average load × average electricity price) calculates, and loss of outage amounts to 11000*65 hours=710,000 yuan, then using the dress
Put half a year, save 74.9 ten thousand yuan of expense altogether.
Social benefit：The device is easy to use, strong applicability, shortens cable fault power off time, avoids secondary stop
Electricity, one is reduction of Customer Complaint rate, and it is horizontal to mark to improve teams and groups；Second, improving power supply reliability, improving client expires
Meaning degree, by the favorable comment of various circles of society, good electric service image is moulded.
