Description
Technical field
The present invention relates to a kind of high voltage converter, belong to power domain.
Background technology
High voltage converter is widely used in metallurgy, mine, electric power, petrochemical industry, cement, plumbing and centralized now
High-field electrode frequency control in the various fields such as middle air-conditioning, becomes enterprise and uses the preferred unit of energy-saving of motor system mode.
High voltage converter is typically spelled cabinet by single transformer case, power unit cabinet, control system cabinet and four, input and output cabinet part
Composition.Many high voltage converter composition cabinets are many in the market, and floor space is big, needs to take out stitches in packaging, transportation
Divide cabinet, to spelling cabinet wiring during in-site installation again, add dismounting and the workload installed.The open explanation of Chinese utility model patent
Book CN200994042Y discloses a kind of integrated high-voltage transducer, the cabinet formed with cabinet door including base, metal framework,
In cabinet, it is divided into the three-phase converter module that multilamellar is placed, sealing plate on rear side of side plate, cover plate, cabinet surrounds with base baffle
Annular seal space, and it is arranged on the blower fan of annular seal space top layer, frequency converter cabinet body is divided into upper and lower two-layer by central dividing plate, and lower floor is provided with water
The transformator of placing flat, upper sheaf space is divided into two parts before and after multilamellar, is used for placing power cell, and wherein installation power list
The few space that cabinet soared, has more than needed of unit is used as placing control room and the altitude chamber of output wiring terminal of control system,
The rear side sealing plate of the power cell placed before and after in upper sheaf space is with the side plate of cabinet both sides, top cover plate and central dividing plate
Surrounding an annular seal space, this annular seal space top is provided with cooling blower.The power cell of this patent is placed on sheaf space on cabinet
Before and after two parts, i.e. power cell be arranged to two relative row's structure, for convenience power cell wiring, power cell defeated
Go out end and be positioned at side before and after frequency converter cabinet body, so that the electric capacity in power cell is near sealing plate, due to cooling blower position
In the top of annular seal space, in cooling procedure, cooling wind flows to annular seal space from the outside of frequency converter cabinet body, by annular seal space
The cooling blower of side is extracted out and is gone, and when cooling down wind and taking away substantial amounts of heat, the cooling wind in annular seal space is than atmospheric environment temperature
Degree height, near sealing plate electric capacity long-term work at high temperature, can significantly cause the reduction in electric capacity service life, and power cell
Determine the service life of whole power cell the service life of middle electric capacity, thus cause the decline in power cell life-span.Therefore
The high voltage converter of integration is to reducing the size of converter, cost-effective and improve performance and have extremely important effect.
High voltage converter internal circuit is more, and it easily generates heat and causes fire, but current high voltage converter lacks automatically
Detect its internal temperature to judge inside it whether to cause the function of fire and the function of self-extinguishing because of short circuit, therefore work as height
Cause concrete on fire can not to put out a fire in time, in easily causing high voltage converter inside voltage frequency changer because of short circuit and heating
, there is the biggest potential safety hazard in the larger range of short circuit of portion's circuit and cause larger range of fire.
