Abstract
The invention discloses a rapid combined air supplement device for a 10 kVSF6 gas insulated metal enclosed switch cabinet. The device comprises an SF6 gas cylinder, a pressure reducing valve, a female joint and a plurality of taps, wherein the SF6 gas cylinder, the pressure reducing valve, the female joint and the taps are sequentially connected. Each tap is a self-sealing quick insertion type joint, and the air supply end of each tap is in threaded connection with the air outlet end of the female joint. The air outlet end of the above tap is connected with the air supplement port of the SF6 gas insulated metal enclosed switch cabinet. The air supply ends of all the plurality of taps are designed in the unified standardization manner. The air outlet ends of the plurality of taps are matched with the air supplement ports of the SF6 gas insulated metal enclosed switch cabinet connected therewith. When a novel type of 10 kVSF6 gas insulated metal enclosed switch cabinet is added, only one air supplement joint that is well matched with the female joint and the air supplement port needs to be added in the above combined device. Meanwhile, no extra set of air supplement device is required. Therefore, the air-supplementing overhaul time of SF6 inflating type electrical equipment is shortened, and the working efficiency is improved.

Exhibition.With rapid economic development, China's power system capacity drastically expands, in recent years, SF6 gas-insulated metal enclosed switchgear cabinets
Consumption further increases.
The effect in the electrical apparatus of SF6 gases is arc extinguishing and insulation, but, if SF6 is gas-insulated metal-enclosed opened
Density reduction (leakage that such as manufacturer's product quality, unit in charge of construction's mounting process cause) in cabinet is closed, SF6 will be caused to inflate
Formula inside electric appliance pressure declines, insulation is reduced, and has a strong impact on the electric property of SF6 equipment, and safe operation is caused seriously
Hidden danger.In order to ensure the reliability service of SF6 gas-insulated metal enclosed switchgear cabinets, the continuous reliability service energy of power system is improved
Power, just must carry out tonifying Qi to SF6 gas-insulated metal enclosed switchgears cabinet in time, and need the tonifying Qi must just to have making-up air device.
But, due to the SF6 switch cubicles of each producer model and differ, therefore each model SF6 switch cubicles often
It is equipped with and different fills making-up air device.And these it is different fill between making-up air device often compatible poor performance, this is not only caused
The very big wasting of resources, and as newly-increased making-up air device is more and more, often there is the risk lost；While substantial amounts of benefit
Device of air is also for keeping storage causes very big inconvenience.So when filling tonifying Qi maintenance to shorten SF6 inflatable electrical equipments
Between, improve operating efficiency, it is ensured that SF6 inflatable electrical equipments put into operation safely, power supply reliability and security are improved, having very much must
A set of SF6 gas-insulated metal enclosed switchgears cabinet Rapid Combination making-up air device is developed, scene is according to SF6 inflatable electrical equipments
Model is quickly assembled, to meet the Maintenance and Repair needs of the SF6 inflatable electrical equipments of various models.
The content of the invention
Regarding to the issue above, the present invention provides 10kVSF6 gas-insulated metal enclosed switchgear cabinet Rapid Combination making-up air devices.
The purpose of the present invention is realized using following technical scheme：
10kVSF6 gas-insulated metal enclosed switchgear cabinet Rapid Combination making-up air devices, including be sequentially connected SF6 gas cylinders,
Pressure-reducing valve, female joint and tap, the tap are the outlet side screw thread of self-styled fast insertion type joint, its air-inlet and female joint
Connection, its outlet side is connected with the gas supplementing opening of SF6 gas-insulated metal enclosed switchgear cabinets；The tap equipped with multiple, often
The air-inlet of individual tap is using unified standardization design, its outlet side and the SF6 gas-insulated metal enclosed switchgears being connected
The gas supplementing opening of cabinet matches.
Preferably, it is additionally provided with hand-operated valve on the pipeline between the SF6 gas cylinders and pressure-reducing valve.
Preferably, connected by flexible pipe between pressure-reducing valve and female joint.
Preferably, it is additionally provided with pressure gauge on pressure-reducing valve.
Beneficial effects of the present invention are：The making-up air device uses modular design, convenient disassembly, highly versatile, tap
Air-inlet designed using unified standardization, in the female joint as facilitating different taps accesses, as long as previously according to not
With different taps are got ready, then a set of combined type making-up air device can meet Multiple Type and open the gas supplementing opening of same model switch cubicle
The tonifying Qi demand of cabinet is closed, is equipped with for a set of making-up air device compared to a kind of model switch cubicle at present, greatly save cost.Simultaneously
As 10kVSF6 gas-insulated metal enclosed switchgear cabinets put into operation being continuously increased of quantity species, this set combination making-up air device it is low
Cost advantage is more obvious by what is embodied, when the 10kVSF6 gas-insulated metal enclosed switchgear cabinets of new type are increased, only need to be
Increasing by one in combination unit can be with female joint and the tonifying Qi joint of gas supplementing opening good match, it is not necessary to extra to prepare new
A whole set of making-up air device, shorten SF6 inflatable electrical equipments fills the tonifying Qi repair time, improves operating efficiency.
