Abstract
The invention relates to an electrical tool, in particular to a joint for measuring sulfur hexafluoride water content of a unit switch. The joint comprises a baseplate, a bolt, a port arranged in the middle of the baseplate, and an alarming device used for prompting leakage. Contact conditions of the undersurface of the baseplate can be effectively observed through a reflector, so that convenience is brought to operating personnel to use the joint. The alarming device is arranged on a sealing ring, and when the sealing ring leaks, a buzzer alarms to prompt the operating personnel to take measures, so that reliability in working is improved. The joint is remarkable in effect, safe and reliable.
Description
Technical field
The present invention relates to a kind of electric power tool, be specifically related to a kind of unit switch sulphur hexafluoride moisture measurement joint.
Background technique
Unit switch, as the visual plant of unit, in the time of the normal start and stop of unit, as set grid-connection and splitting point, in the time of unit generation electrical failure, works to disconnect larger electric current.Unit switch adopts box-type sulphur hexafluoride insulation circuit breaker, the operation of hydraulic pressure three-phase ganged more at present.According to " electrical equipment preventive test code " requirement, need the water content of periodic measurement unit switch sulfur hexafluoride gas indoor gas, guarantee the good insulating property of sulfur hexafluoride gas in unit switch, ensure the normal disjunction of unit switch.Because unit switch adopts imported product, and sulfur hexafluoride gas sounding pipe pipeline connector is not to adopt NBS, therefore regularly unit switch being carried out to experimental measurement cannot implement, water content and the variation tendency thereof that can not regularly grasp unit switch sulfur hexafluoride gas, this has just left hidden danger to the safe and stable operation of unit switch.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of can connect simultaneously unit switch sulfur hexafluoride gas chamber and surveying instrument, observation convenient, separate fast, reveal early warning, reduce unit switch operation risk and improve the unit switch sulphur hexafluoride moisture measurement joint of equipment reliability.
For solving above technical problem, the present invention adopts following technological scheme: the present invention includes base plate, bolt, be arranged on the interface at base plate middle part and for pointing out the warning device of leakage; On described base plate, be arranged with two screws, described bolt is arranged on measured piece through screw, and described interface and base plate contacting point are provided with seal ring, and described interface middle part is provided with through hole, and middle part, described base plate bottom surface is provided with skin mouth, and described skin mouth communicates with through hole;
Described warning device comprises battery and buzzer, and described battery and buzzer are linked in sequence successively, and is connected with seal ring by wire.
Described base plate side is provided with crossbeam, and described crossbeam is provided with reflecting mirror.
The present invention also comprises handle and rubber rods, and described handle is symmetrically set in base plate two parallel surfaces, and described rubber rods is evenly arranged on base plate bottom surface.
The model of described battery is CR2032 li-Mn button cell, and the model of buzzer is COLICOLI3V active buzzer.
Good effect of the present invention is as follows: the present invention is simple in structure, easy accessibility, and the setting of rubber rods and handle is easier when base plate is separated with measured piece, has effectively avoided because of the less not segregative phenomenon of base plate and measured piece gap; Base plate bottom surface of the present invention is provided with skin mouth, and this just makes sampling process stable, is difficult for producing and reveals; The present invention can effectively observe base plate bottom surface contact situation by reflecting mirror, and this has just facilitated operator's use; The present invention is provided with warning device on seal ring, in the time that seal ring produces leakage, and buzzer warning, alert is taken measures, and has improved the reliability of work, successful and safe and reliable; The present invention, for the test of unit switch sulfur hexafluoride gas water content provides medium, has reduced because testing the equipment safety operation risk of bringing not in place.
