Abstract
The utility model is related to electric power it is comprehensive from station, it is secondary debugging check and accept etc. working site detection instrument, specially portable protection measurement and control signal verifier.Portable protection measurement and control signal verifier; including housing; rotary switch, public end interface and some LEDs are provided with housing; the back of housing is further fixed on some contact pins; the gear of rotary switch, the quantity of LED are identical with the quantity of contact pin, and the contact with a gear of rotary switch, a LED and a contact pin concatenate to form a short circuit loop public end interface respectively.Portable protection measurement and control signal verifier, solve when electric power overhaul working site is opened into contact checking signal by short circuit signal and easily touch other terminals by mistake, cause the security risk of direct-current short circuit or breaker mistrip accident.The security of this work is improved, while improves operating efficiency.
Description
Technical field
The utility model is related to electric power it is comprehensive from station, it is secondary debugging check and accept etc. working site detection instrument, tool
Body is portable protection measurement and control signal verifier.
Background technology
Electric power it is comprehensive from station, it is secondary debugging check and accept etc. working site, it is necessary to check hard contact remote signals, core
To opening the method into signal usually using the hard contact of short circuit observing and controlling, to verify telemechanical storehouse and master station automation front end processor telemechanical storehouse
Uniformity.Operation field opens the mode analog signal hair into contact generally by maintainer using short line short circuit signal at present
Send, complete this work.At work, staff conscientiously must carefully prevent short line from touching other terminals by mistake, otherwise may
The serious accidents such as switch trip, direct-current short circuit can be caused.
The content of the invention
The utility model is in order to solve the above problems, there is provided portable protection measurement and control signal verifier.
The utility model adopts the following technical scheme that realization：Portable protection measurement and control signal verifier, including shell
Body, rotary switch, public end interface and some LEDs are provided with housing, the back of housing is further fixed on some contact pins, rotation
The gear of switch, the quantity of LED are identical with the quantity of contact pin, and public end interface is tactile with a gear of rotary switch respectively
Point, a LED and a contact pin concatenate to form a short circuit loop.
Above-mentioned portable protection measurement and control signal verifier, the back of housing is additionally provided with neck.Neck in back side of shell,
Device card can be made reliably to be removed and installed in terminal block.
Public end interface is inserted using wire, the wire other end is connected with protection measurement and control signal loop common port, and contact pin is inserted
Enter and be reliably connected to form short circuit with terminal block in DC terminal row.Knob controls change-over switch, allows short circuit loop from obstructed
Any contact pin is switched to, when LED is bright, the short circuit of signal open entry loop where contact pin corresponding to representative.
Portable protection measurement and control signal verifier is set about from conveniently, safely angle, in checking signal, temporarily by verifier
Arranged installed in signal terminal in screen, opened by operating verifier knob come short circuit signal into terminal, avoid the behaviour in work
Make risk, and improve the reliability of signal verification.Portable protection measurement and control signal verifier, solves electric power overhaul work
Other terminals are easily touched in scene by mistake when being opened by short circuit signal into contact checking signal, cause direct-current short circuit or breaker mistrip
The security risk of accident.The security of this work is improved, while improves operating efficiency.
