Abstract
The utility model discloses a kind of Power Secondary work peace and arrange tool set, it includes pressing plate protective cover, sky opens jig, CT short-circuit piece, terminal board purse seine and BUSHING.Power Secondary work of the present utility model peace arranges tool set, can realize secondary maintainer work standardization, specialized management, guarantee work about electric power fail safe.
Description
Technical field
The utility model relates to a kind of electric operating managing security tools and instruments, the safe tool set particularly in the work of a kind of power industry secondary.
Background technology
Regulation in Guo Wang company " electric power safety working regulation ", following secondary work should be filled out with secondary work safety ticket: 1. carry out tearing open on the secondary circuit of operational outfit, wiring work; 2., when performing quarantine measures to repair apparatus, need split off, short circuit and recovery be with the associated secondary circuit work of operational outfit.Therefore, corresponding safety measure should be arranged before the work of power industry secondary starts, after end-of-job, corresponding safety measure should be recovered.But secondary maintenance teams and groups do not arrange the specific purpose tool of secondary safety measure, and it is blank to arrange tool set field to exist in secondary work peace in the industry at present, not can be applicable to on-the-spot standard, the specific purpose tool of specification.
1., in work on the spot, secondary specialty catastrophe risk point mainly comprises five aspects: 1. during equipment component interruption maintenance, the relay-protection pressing plate of operational outfit jumped by connection; 2., during equipment component interruption maintenance, the voltage sky be connected with charged busbar voltage secondary circuit is opened; 3. during equipment service without power-off, charged current transformer electric current secondary loop; 4. there is multi-compartment equipment, the terminal board of equipment component interruption maintenance luck between-line spacing and secondary line in same protection screen or observing and controlling screen; 5. the interim secondary line removed.Duration of work is all relates to above dangerous spot, and according to the requirement of secondary work, the relay-protection pressing plate that operational outfit jumped by connection must be removed, and must not drop into, otherwise can cause power failure by false tripping operational outfit.For the pressing plate removed, in order to prevent from miscarrying into, adopt the wrapping of red insulating tape at present, shortcoming is that adhesive plaster easily comes off, wastes material.According to secondary work
2. requirement, during equipment component interruption maintenance, busbar voltage secondary sky is opened and must be disconnected, and prevents reverse charge.Open to prevent closing sky by mistake, after disconnection sky is opened at present, only adopt red insulating tape to identify, adhesive plaster easily comes off, and because repair apparatus place sky is opened more, easily close sky by mistake and open, this kind of measure is unreliable.According to the requirement of secondary work, electric current secondary loop must not be opened a way, and no person can produce high voltage, threatens to the person, equipment.Therefore, when the current transformer electric current secondary loop run works, must take safety measures.Traditional method adopts special shorting stub or short circuit sheet short circuit secondary circuit, and this way shortcoming causes open circuit after easily touching pine.During secondary work, if there is multiple interval in same equipment screen, during single interval interruption maintenance, the terminal board running interval must take quarantine measures, avoids malfunction operational outfit.Mark pasted by the red insulating tape of current employing, and shortcoming is that adhesive plaster easily comes off, wastes material.The secondary line of interim dismounting.The secondary line of interim dismounting is general all charged, if effectively do not wrap up, easily touch device housings, even other electric loop wiring, cause short circuit or ground connection by mistake.In work on hand, the red insulating tape wrapping of general employing, easily comes off, and lacks effective mark.
