Abstract
The utility model relates to a kind of discharge coil; comprise casing, the iron core of box house, the electric discharge winding and the secondary winding that are wound in both sides unshakable in one's determination respectively and the high tension terminal be connected with secondary winding with electric discharge winding be respectively arranged at above casing and low tension terminal; described low tension terminal upper end is provided with safety indicating device; described safety indicating device comprises insulating coating; cavity is established in insulating coating; be provided with protective resistance, ammeter, spring and the hand touched electrode of connecting successively in cavity, insulating coating front end is provided with the screwdriver of connecting with protective resistance.The utility model structure is simple, can record discharge coil easily and whether the electricity of Capacitor banks is discharged into below safe voltage, for the safety of maintainer provides safeguard.
Description
Technical field
The utility model relates to a kind of coil, is specifically related to a kind of discharge coil being usually used in shunt capacitor.
Background technology
When Capacitor banks power-off, discharge coil is used for the electric field energy of Capacitor banks discharging safely and fast, safety during to ensure Capacitor banks reclosing and the safety of attendant, but whether this discharge coil is discharged into below safe voltage the electricity of Capacitor banks, need to measure further, waste time and energy.Maintenance personal reaches when safe voltage is keeped in repair and can threaten to its personal safety takeing for electric discharge.
Summary of the invention
For the problems referred to above, the utility model provides a kind of discharge coil that can clearly indicate level of security, fail safe higher.
For solving the problem, the technical scheme that the utility model is taked is: a kind of discharge coil, comprise casing, the iron core of box house, the electric discharge winding being wound in both sides unshakable in one's determination respectively and secondary winding and the high tension terminal be connected with secondary winding with electric discharge winding be respectively arranged at above casing and low tension terminal, described low tension terminal upper end is provided with safety indicating device, described safety indicating device comprises insulating coating, cavity is established in insulating coating, the protective resistance of connecting successively is provided with in cavity, ammeter, spring and hand touched electrode, insulating coating front end is provided with the screwdriver of connecting with protective resistance.Tester, by finger contact hand touched electrode, observes ammeter registration, and join protection resistance judges whether the voltage after discharging reaches safe voltage.
Electric capacity and the electric bell of series connection mutually is also provided with in described cavity, in parallel with ammeter after the series connection of electric capacity, electric bell.Tester is by finger contact hand touched electrode, and when low tension terminal voltage is greater than safe voltage, electric bell gives a warning, and when low tension terminal voltage is within safe voltage, electric bell does not send sound.The installation of electric bell can make up ammeter and measure the inaccurate mistake produced, and prevents tester from judging by accident.For the personal safety of maintainer provides double shield, and the warning that electric bell sends more easily causes the attention of maintainer.
Low tension terminal is fixed on described screwdriver top.Such low tension terminal, safety indicating device, human body and the earth form closed-loop path.
Described protective resistance resistance is 500 ohm.
For ease of dismounting hand touched electrode, change inner member.Described hand touched electrode is connected with spring and screw thread is rotatably connected in insulating coating end.
The utility model structure is simple, can record discharge coil easily and whether the electricity of Capacitor banks is discharged into below safe voltage, for the safety of maintainer provides safeguard.
