Description
Technical field: the invention belongs to the charged display device that high-tension switch gear is used, particularly a kind of electrification in high voltage shows electroscopic device.
Background technology: existing pressure type high voltage display device locking principle is too simple, A, B, C three-phase sensor output signal is carried out after the half-wave rectification directly together compound respectively, removes to control locked loop.When single-phase earthing or phase shortage abnormal conditions appear in this mode system, because of the drift of locking control voltage can cause device reliably locking electric misoperation takes place, accidents such as mistakenly entering charged chamber, charged splice grafting ground switch.Secondly, high-voltage switch gear uses the high voltage display device of neon lamp as display element cashier's office in a shop in a large number at present, and long-play uses, and finds that blind rate is high, and a large amount of the damage appears in neon bulb.For supplying a gap, installed neon lamp operation/off switch on the charged display device, this switch is in closed condition at ordinary times, makes whole high voltage display device temporarily out of service.This processing mode has lost high voltage display device as the whether charged effect of monitoring wire.
This shows; Design a kind of have adopt LED charactron display and flash-mode electrical verification plug-in unit constitute dual demonstration, electrified voltage shows and on-the-spot independent electrical verification and nuclear phase function, utilize phase-splitting to detect digitizing stack locking control technology when guaranteeing system's phase shortage misoperation, blocking voltage is constant and electrification in high voltage demonstration electroscopic device that reach stable operation is necessary.
The electrification in high voltage of prior art shows that electroscopic device can only show that each is mutually charged whether, can not show electrified voltage.And the electrification in high voltage that the present invention implements to obtain shows that electroscopic device not only can show that each is mutually charged whether by 3 mutually electric pilot lamp, and electrified voltage also can read from LED charactron display; Adopt LED charactron display to compare as the high voltage display device of display element with the neon lamp of prior art, long-play uses blind rate low, does not exist display device temporarily out of service, has lost the whether charged defective of monitoring wire.
After the plug of independent electrical verification/phasing tester flash-mode electrical verification plug-in unit inserts the electrical verification/phasing tester flash-mode electrical verification plug-in unit socket on the supporting with it body panel; Utilize the detection head of the plug body other end can carry out independent electrical verification, and from the flash of light of electrical verification/nuclear phase pilot lamp, obtain showing; Utilize independent electrical verification/phasing tester flash-mode electrical verification plug-in unit can also carry out nuclear phase operation: to stir the A phase position of toggle in the A/B/C of phase place index line on the body panel; The A phase that needs another high voltage electric equipment of test phase sequence again with the detection head connection of independent electrical verification/phasing tester flash-mode electrical verification plug-in unit; If flash of light does not appear in electrical verification/nuclear phase pilot lamp; Judge that then phase sequence is identical,, judge that then phase sequence is different if flash of light appears in electrical verification/nuclear phase pilot lamp; The method of testing of other B, C phase is identical.
2, utilize phase-splitting to detect digitizing stack locking control technology when guaranteeing system's phase shortage misoperation, blocking voltage is constant and reach stable operation.With the pressure type high voltage display device locking of prior art A, B, C three-phase sensor output signal are carried out respectively after the half-wave rectification directly compound; Go to control the locked loop difference; The electrification in high voltage that the present invention implements to obtain shows that electroscopic device adopts phase-splitting to detect digitizing stack locking control technology; During assurance system phase shortage misoperation, blocking voltage is constant and reach stable operation.Promptly when single-phase earthing or phase shortage abnormal conditions occurring, the drift of locking control voltage can not cause reliably locking and electric misoperation takes place, accidents such as mistakenly entering charged chamber, charged splice grafting ground switch of device.As long as the electromagnetic lock of supporting with it execution forced blocking function or the supply voltage of relay are higher than rated voltage 65%, electromagnetic lock or the relay of carrying out the forced blocking function still have reliable forced blocking function.
Only not charged at matching used high-voltage electrical equipment and electrification in high voltage that the present invention implements to obtain shows when electroscopic device has accessory power supply; When the release pilot lamp on its body panel lights; Electric release just is provided; Let operating personnel overhaul and contact high-voltage electrical equipment, this has just guaranteed the enforcement that " five is anti-" requires.
Summary of the invention: the deficiency that the objective of the invention is to overcome prior art; Design a kind of have adopt LED charactron display and flash-mode electrical verification plug-in unit constitute dual demonstration, electrified voltage shows and on-the-spot independent electrical verification and nuclear phase function, utilize phase-splitting to detect digitizing stack locking control technology when guaranteeing system's phase shortage misoperation, blocking voltage is constant and reach the electrification in high voltage demonstration electroscopic device of stable operation.
