Description
Technical field
The utility model relates to controller switching equipment inspection technology field more particularly to a kind of SF for adapting to strong-electromagnetic field environment6
Quantitative testing device.
Background technique
Currently, using SF6Gas density relay is monitoring SF6The main means of inside electric appliance pressure change, once
Equipment internal gas pressure drops to density monitor alarming value, that is, illustrates that more serious SF occurs in equipment6Leakage is existing
As leakage point need to be found out rapidly before air pressure continues to drop to locking value or to leakage equipment tonifying Qi to rated value, otherwise
Equipment built-in electrical insulation can be punctured, caused the accident.
Currently, SF6There are two types of detection means when equipment leaks: (1) offline inspection, such as bandaging strapping, gas component
Method etc. need to have a power failure, and it is big to run the leak test plant that on duty or service personnel is equipped with because equipment is in operating status to scheduling application
The mostly qualitative leak detector of handheld portable, leak detector probe are allowed for directly contacting or could be reported very close to leakage point
Alert or display leakage concentration, brings inconvenience for quickly processing defect；(2) live detection, such as infrared leak detector, though this detection is not
Have a power failure, but the equipment (breaker, the mutual inductor of such as 220kV and above) of voltage levels is very high away from ground,
Service personnel is too big to the difficulty detected at the top of equipment, while aloft hunting leak unavoidably by the shadow of wind speed
It rings, wind speed is more than leak detector scope of design, and leak detector equally alarms, causes to report by mistake.
Currently, the SF that the current transformer and breaker to substation carry out6Quantitative detection is carried out under power blackout situation,
It there is no the SF that can be worked in the energized state6Leak detector.It can carry out SF6There are many equipment of detection, these SF6Leak detector is main
Including host and display screen, leak detector secures a hand-held probe, is connect by pipe joint with host, operator passes through
Display screen monitors survey measurements.Since the current transformer and breaker decorating position of 220kV application are higher, existing SF6It is fixed
Amount leak detector is difficult to carry out quantitative detection, and main difficulty is SF6Quantitative leak detector will charge CT in substation and breaker
In the case of carry out SF6Quantitative leak detection, it is necessary to have the stabilization under strong-electromagnetic field environment, reliably detect work capacity,
Otherwise high-precision, the quantitative detection of high stability, and existing SF are difficult to realize6Quantitative leak detector does not have this ability also.
Utility model content
The utility model provides a kind of SF for adapting to strong-electromagnetic field environment6Quantitative testing device can adapt to strong-electromagnetic field
Environment simultaneously carries out real-time, accurate, stable quantitative detection.
In order to achieve the above objectives, the embodiments of the present invention adopt the following technical scheme that
A kind of SF adapting to strong-electromagnetic field environment6Quantitative testing device includes host, display screen, data-interface, power supply
Interface and hand-held probe further include having an electromagnetic shielding box, and the host is arranged inside the electromagnetic shielding box, described
Display screen, data-interface, power interface are separately positioned on the electromagnetic shielding box side wall, the display screen, data-interface, electricity
Source interface is connect with the host respectively, and the hand-held probe is set to outside the electromagnetic shielding box, passes through pipe joint
It is connect with the host.
Further, the material of the electromagnetic shielding box is iron.
Further, the electromagnetic shielding box sealed set.
The beneficial effects of the utility model are: the utility model is existed host setting by one electromagnetic shielding box of setting
In electromagnetic shielding box, the material of electromagnetic shielding box is iron, and the shielding action by electromagnetic shielding box to electric and magnetic fields can make
Host is still able to carry out power equipment SF under electrification and forceful electric power magnetic environment6The detection of Air Leakage Defect, to realize in forceful electric power
Real-time, accurate, stable quantitative detection is carried out under magnetic field environment.
