A kind of electric operating fuse wire protection tool that do not have a power failure
Technical field
The utility model relates to a kind of electric operating construction protective device, and especially, the utility model relates to a kind of electric operating fuse wire protection tool that do not have a power failure.
Background technology
Up to now; with 10kv and under the power supply of transmission line to city, enterprise etc. in; for guaranteeing power supply safety; normally in being connected of transformer of three-phase power line and power supply user; the fault fuse is set between three-phase line and transformer respectively; in case the overvoltage electric current flows into, then this fault fuse is a blow out fuse, and power supply user's power consumption equipment is protected.
Yet, need to above-mentioned 10kv and under transmission line overhaul, change, perhaps,, must overhaul, during transposing etc., just must interrupt above-mentioned single-phase or three-phase circuit temporarily because of above-mentioned fuse damages.
At this moment, guarantee continuously to power, particularly, guarantee 10kv and under the power supply reliability of transmission line, simultaneously, guarantee to provide the power supply quality of high-quality, be the fast-developing necessary of every profession and trade.Yet, as mentioned above, power supply circuit, particularly 10kv and under the electric operatings such as maintenance of transmission line the time, usually need power circuit is temporarily disconnected, so that maintenance.For this reason, the electric operating that requires maintenance not have a power failure, that is, and require to above-mentioned 10kv and under transmission line and fuse thereof do not overhaul with having a power failure, operation such as transposing.
For reaching the requirement of the electric operating that do not have a power failure, adopted the exchanging closed fuse device of 10kv circuit in the past.The exchanging closed fuse device of described 10kv circuit for example adopts mostly, the direct-connected operating type of drainage thread.
According to described traditional live line working mode, promptly adopt the direct-connected operating type of drainage thread, that is, directly connect transposing single-phase (or three-phase) load fuse device, simultaneously, with the interim power consumption equipment that directly is connected in series above-mentioned single-phase or three-phase power line and transformer or user of another lead.Obviously, at this moment,, then will make this phase circuit equipment and hotline maintenance personnel in a period of time lose protection in case the overvoltage electric current flows into.In addition, if break down this moment, as easy as rolling off a logly cause the circuit action of bypassing the immediate leadership, expansion accident scope causes seriously potential safety hazard such as device damage and personnel casualty accidents.Have again, adopt the direct-connected operating type of drainage thread that labor intensity of operating personnel is increased, operation inconvenience.
For this reason, press for and a kind ofly promptly can be convenient for changing fuse device, can protect the electric operating fuse wire protector without electricity failure of equipment and live line working personal security again.
