Abstract

The utility model relates to a transducer, in particular to a high voltage transducer which is suitable for general machinery such as hoists, winches, belt conveyors, rolling mills, and which takes an insulation gate semiconductor high speed switch power module (IGBT) as a main component. The AC input of the transducer is sequentially connected with a rectifier unit, a filter unit, and an inverter unit by a high voltage breaker, and is finally output to an output terminal load; wherein, the insulation gate semiconductor high speed switch power modules (IGBT) adopted by the inverter unit are directly connected with each other in series; furthermore, a brake unit is additionally arranged in the filter unit. As the IGBT is taken as the main component of the transducer, the general machinery adopting the transducer such as centrifuges, hoists, winches, belt conveyors, rolling mills and so on have large speed regulation range, small loss, wide applicable load range, and are easy to implement the positive and reversed rotation shift and to constitute an automatic control system, with low starting current, and are used for the sites of frequent starting and braking.

Description

Universal machine type high voltage converter
Affiliated technical field
The utility model relates to a kind of frequency converter, and especially a kind of employing Iusulated gate semiconductor speed-sensitive switch power model (IGBT) is the universal machine type high voltage converter of critical piece.
Background technology
Universal machine such as a large amount of elevator, winch, belt feeder all needs to carry out speed regulation in the industrial production.And the speed regulating device that use in the prior art have increased the complexity of system, have also caused a large amount of wastes of the energy.Therefore, people wish to adopt the ac motor speed control system to replace dc motor speed-regulating system always, and have carried out a large amount of research and developments.
Developed multiple ac motor speed control device for many years, as: stator variable voltage speed control, pole changing, slip regulating speed, electromagnetic coupler speed governing, tandem control, commutator machine speed governing etc.Though succeeding in developing of these governing systems obtained certain achievement, but still exist shortcomings such as speed adjustable range is narrow, loss is still bigger than normal, power factor is low, suitable load surface is narrow, thereby limited the application of these Alternating Current Governor Systems.
The utility model content
The purpose of this utility model is to provide a kind of speed-regulating range width, little, the suitable load of loss is wide and the universal machine type high voltage converter of energy fast braking.
The technical solution of the utility model is achieved in that the interchange input 1 of high voltage converter through primary cut-out 2 and rectification unit 3, filter unit 4, and inversion unit 5 connects in turn, outputs to output load 6 at last.Wherein the Iusulated gate semiconductor speed-sensitive switch power model that adopts in the inversion unit 5 is directly series connection each other.In filter unit 4, increased simultaneously the brake unit of forming by brake control section part 9 and brake resistance 87.
The beneficial effects of the utility model are:
Adopting IGBT is that the speed adjustable range of universal machine type high voltage converter of critical piece is big and continuously, realizes that easily forward and backward switches and constitute automatic control system, and starting current is little, can be used for Fraquent start and fast braking occasion.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is a converter circuit schematic diagram of the present utility model.Among the figure 1, exchange input, 2, primary cut-out, 3, rectification unit, 4, filter unit, 5, inversion unit, 6, the output load, 7, brake unit, 8, brake resistance, 9, the brake control section part.
Embodiment
In Fig. 1, the interchange of high voltage converter input 1 process primary cut-out 2 and rectification unit 3, filter unit 4, inversion unit 5 connects in turn, outputs to output load 6 at last.Wherein the Iusulated gate semiconductor speed-sensitive switch power model that adopts in the inversion unit 5 is directly series connection each other.In filter unit 4, increased simultaneously the brake unit of forming by brake control section part 9 and brake resistance 87.For high voltage converter of the present utility model, it exchanges input 1 is the power frequency of 3-10KV, and its output load can connect elevator, winch or belt feeder etc.
