Suppress cabinet can install the devices such as microcomputer harmonic elimination, small current earthing wire-selecting, Intelligent control additional simultaneously, achieve one-machine-multi-function, save on-the-spot limited space.
But in actual production, the switch cubicle of current medium voltage network is mostly intermediate switchgear cabinet, and overvoltage suppression cabinet is generally fixed switching cabinet, inconsistent with other switch cubicle in system, impact is on-the-spot attractive in appearance; Carry out input coefficient with timer by isolating switch or exit from system, inconsistent with the miscellaneous equipment at scene, operation and maintenance are made troubles, produces to user security and bring certain hidden danger.
Utility model content
The purpose of this utility model is to provide the intelligent overvoltage inhibiting apparatus of a kind of HYDP, isolation handcart in this device can replace the isolating switch in conventional overvoltage suppression cabinet, makes on-the-spot switch cubicle outward appearance consistent, structural similarity, mode of operation is consistent, brings convenience the maintenance of user.
To achieve these goals, the utility model is by the following technical solutions: the intelligent overvoltage inhibiting apparatus of a kind of HYDP, comprises secondary chamber, isolation handcart, PT fuse-carrier, PT fuse, intelligent instant shut-in, PT voltage transformer, resonance eliminator, high voltage bus room, high-voltage and current-limitation fuse and a peak overvoltage absorber; High-tension electricity is introduced in cabinet by busbar by isolation handcart from high voltage bus room, arriving after in cabinet is divided into two-way in parallel, wherein a road high-tension electricity is received on peak overvoltage absorber by three phase mains by high-voltage and current-limitation fuse, and another road high-tension electricity is received on PT voltage transformer after PT fuse.
Further, the controller for judging PT voltage transformer secondary signal is installed in described secondary chamber.
Further, described PT voltage transformer neutral point is by parallel with intelligent instant shut-in a resonance eliminator ground connection.
Further, described intelligent overvoltage inhibiting apparatus is a whole cabinet, and cabinet is the KYN28 cabinet of standard;
Preferably, described intelligent overvoltage suppression cabinet is during overhaul of the equipments or stoppage in transit, and the isolation handcart in cabinet will move test position to, and element and system in cabinet are departed from completely.
Beneficial effect:
The utility model compared with prior art, has following beneficial effect: the most important effect of the utility model is that isolation handcart replaces isolating switch, and make on-the-spot switch cubicle outward appearance consistent, structural similarity, mode of operation is consistent, brings convenience the maintenance of user.Solve the intermediate switchgear cabinet of medium voltage network and the fixed switching cabinet of Overvoltage suppressing, inconsistent with other switch cubicle outward appearance in system, the on-the-spot problem attractive in appearance of impact.The utility model solves isolating switch and is built in cabinet, due to narrow space in cabinet, not easy to operate, easily damages the problem of the hand of operating personnel when misoperation.
Meanwhile, the utility model solves device to be carried out input coefficient by isolating switch or exits from system, inconsistent with the miscellaneous equipment at scene, makes troubles, produce the problem bringing certain hidden danger to user security to operation and maintenance.
