What is a high-pressure inflatable cabinet? The high-pressure inflatable cabinet is an indoor AC high-voltage gas-insulated metal-enclosed switchgear. It mainly seals high-voltage components such as busbars, circuit breakers, disconnectors, transformers, etc. at a lower pressure (0.1~). In the housing of 0.5mpa)sf6 or other gases, it is composed of air insulation and sulphur hexafluoride gas compartment. It has the characteristics of compact structure, flexible operation and reliable interlocking. The main switch of the high-pressure inflatable cabinet can be used for distribution automation by using a permanent magnet mechanism vacuum circuit breaker or a spring mechanism vacuum circuit breaker.
The structure of the high pressure inflatable cabinet:
The high-pressure inflatable cabinet is divided into three types of structures according to the relative position between the busbar, the isolating switch and the three main modules of the main circuit in the main circuit:
1. Rear and front layout. This is the choice of a gas insulated busbar and an inflatable busbar compartment + busbar connector structure. The typical product is ALSTOM's WS.
2, upper and lower layout. This is the choice of a plug-in solid insulated busbar and an inflated busbar compartment + busbar connector structure, the typical product of which is Mitsubishi's HS-X12.
3. Lower middle and upper layout. This is the choice of the structure of the inflatable busbar room + busbar connector. The typical products are N2S of Shanghai Tianling and ZX1.2 of ABB. This arrangement is not convenient for double busbars.
The main features of the high-pressure inflatable cabinet 1. The inflatable cabinet has a perfect "five-proof" interlocking device to completely eliminate the malfunction of personnel and equipment that may be caused by human error. 2. All switch cabinets of the inflatable cabinet have reliable safety relief channels, even In extreme cases, the operator's personal safety can also be guaranteed.
3. The size of the inflatable cabinet is small and easy to install, and it can be suitable for places with small space and poor environmental conditions.
4. The whole switchgear of the inflatable cabinet is completely unaffected by the external environmental conditions, and the switch can be operated normally even under extreme conditions such as short-time flooding, and the product is maintenance-free for life.
Advantages and advantages of high-pressure inflatable cabinet : strong application performance, good installation performance, high safety performance and high maintenance performance.
Disadvantages: the docking between the production and demand is not secure enough, and the supporting services of the manufacturer have not kept up.
Wire On Tube Condenser air cooled condenser
The condenser which is cooled down of the natural air. this Condenser category as a natural convection type of air cooled condenser which cooled, by the help of natural air.
In construction, it consists of a copper tube Or coil and maybe iron or steel coil upon which iron or steel material of fitted Or soldered together. the flows through the compressed vapour refrigerant in the coil then coil are heated up and supplies it to iron meterial. This iron meterial rejection of the heat, to the atmospheric air.
This type of condenser used in Domestically. For example of the Refrigerators, it's located at the background of the Refrigerators.
