Description
Technical field
The present invention relates to uninterrupted operation service technique fields, and in particular to a kind of uninterrupted operation maintenance auxiliary switch is set
Standby and power grid service without power-off method.
Background technique
Currently, when power supply department encounters scheduled outage or temporary derangement repairing, it can be in the way of bypass operation to overhead line
Road or cable run carry out load transfer power supply and guarantee power supply reliability to reduce power off time.
Wherein, the bypass operation mode of overhead transmission line is as follows: as shown in figure 3, bypass cable 03 is first articulated in faulty section
The two sides in domain are maked somebody a mere figurehead on main line 01, and then by-pass switch 02 closes a floodgate, and transfer main line load finally disconnects Awaiting Overhaul route
Main line switch 011 overhauls route or equipment in power supply interrupted district.Since overhead transmission line is relatively high, by needing several maintenance people
Bypass cable is articulated on overhead transmission line by member by professional tool, and such operation intensity is bigger, and operating cost is high.
Chinese patent literature CN103050892A discloses a kind of bypass operation mode of cable run: first by bypass cable
It is plugged on source side ring network cabinet and cable sleeve by electrical measurement ring network cabinet, then by-pass switch closes a floodgate, transfer main line load,
The switch for finally disconnecting Awaiting Overhaul cable run overhauls route or equipment in power supply interrupted district.Due to bypass cable and ring network cabinet
Cable sleeve before grafting, need of short duration disconnection ring network cabinet, with guarantee grafting safety, after the completion of waiting grafting, then close looped network
Therefore still there is of short duration power-off condition in cabinet.For this purpose, Chinese patent literature CN103078268A discloses a kind of two looped networks
The service without power-off method of 10KV cable run, key step are as follows between cabinet: bypass cable being first plugged in source side looped network
Cabinet and by electrical measurement ring network cabinet standby spacing switch (standby spacing switch function as a ring network cabinet, generally in electricity consumption
Used when dilatation or temporary electricity load rapid growth) cable sleeve on, then close standby spacing switch, then bypass is opened
Lock is closed, transfer main line load finally disconnects the switch of Awaiting Overhaul cable run.Although being realized not by standby spacing switch
Power failure operation, but standby spacing switch occupied space is larger, installs the at high cost of standby spacing switch, so that bypass operation
Operating cost is high.
In addition, since the bypass connecting device of overhead transmission line and cable run is different, in breakdown repair,
In order to cope with different fault conditions, needs to carry simultaneously and be respectively suitable for overhead transmission line and connect dress with the bypass of cable run
It sets, causes service personnel's operation intensity big.
