Description
Technical field
The utility model relates to a kind of overvoltage protection, particularly relates to a kind of extinguishing arc resonance eliminating wire-selection and overvoltage protection
Background technology
At present; be extensive use of its structure of overvoltage protection and mainly comprise tank bracket; be arranged on the voltmeter on the tank bracket; be installed in main bus bar and sleeve pipe in the tank bracket; the isolating switch and the isolator operating mechanism that are connected with main bus bar by last branch bus; be arranged on the post insulator in the tank bracket, be fixed on the post insulator and branch bus is connected with isolating switch under passing through high-tension fuse and overvoltage protection device, and be arranged in the tank bracket and the voltage transformer that is connected with high-tension fuse.Such voltage protection causes the intermittent arc grounding overvoltage because no extinguishing arc, harmonic elimination and route selection function can not be eliminated the intermittent arc grounding fault, causes the further expansion of accident, increases the emergency stop valve trip rate of circuit.Can not limit and eliminate various resonance overvoltages, cause of the accelerated ageing of long resonance overvoltage, reduce the useful life of equipment in the electric power system the power system insulation structure.Can not accurately search the single phase ground fault circuit rapidly, the further expansion that causes the accident increases operation and work of maintenance personnel amount.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of over-voltage protection function that not only has is provided, and also has extinguishing arc, harmonic elimination and route selection function simultaneously, uses safer extinguishing arc resonance eliminating wire-selection and overvoltage protection.
The utility model extinguishing arc resonance eliminating wire-selection and overvoltage protection comprise tank bracket; be arranged on voltmeter and multifunctional microcomputer controller on the tank bracket; be installed in main bus bar and sleeve pipe in the tank bracket; the isolating switch and the isolator operating mechanism that are connected with main bus bar by last branch bus; be arranged on the post insulator in the tank bracket; be fixed on the post insulator and branch bus is connected with isolating switch under passing through high-tension fuse and overvoltage protection device; be arranged in the tank bracket and the voltage transformer that is connected with high-tension fuse; one end is connected the other end and high voltage connector with following branch bus; the series connection of high energy inductance and current transformer and be installed in high-voltage and current-limitation fuse in the tank bracket by post insulator.
The operation principle of the utility model extinguishing arc resonance eliminating wire-selection and overvoltage protection is, forceful electric power is introduced by main bus bar, through last branch bus, isolating switch, following branch bus, post insulator, high-tension fuse is to voltage transformer, this voltage transformer transfers forceful electric power to signal, a part is delivered to voltmeter and is used as measuring, another part is delivered to the multifunctional microcomputer controller and is used as analyzing, find fault-signal as the multifunctional microcomputer controller, just send reclosing command and give high voltage connector, thereby realize main bus bar, last branch bus, isolating switch, high-voltage and current-limitation fuse, post insulator, high voltage connector, the high energy inductance, the loop of current transformer is connected and is reached extinguishing arc, harmonic elimination and route selection function; Aspect in addition, overvoltage is introduced by main bus bar, and through last branch bus, isolating switch, branch bus reaches overvoltage protection device down, this overvoltage protection device discharges automatically, thereby realizes over-voltage protection function.
The advantage of the utility model extinguishing arc resonance eliminating wire-selection and overvoltage protection is to have voltage measurement simultaneously, overcurrent protection, extinguishing arc, harmonic elimination and route selection function relatively reach alternate overvoltage Limiting within the scope of electric power netting safe running with the neutral non-effective grounding electrical network; make such electrical network both keep the advantage of neutral non-effective grounding; again all kinds overvoltage Limiting is arrived alap level; thoroughly solve of the threat of various overvoltage to equipment and electric power netting safe running; improve the power supply reliability of such electrical network, thereby obtained high economic benefit.Be mainly used in the neutral non-effective grounding electric network protection.
