The water-cooled type pulse reactor is provided with good cooling effect.
Description
Technical field
The utility model relates to a kind of water-cooled pulsactor.
Background technology
The magnetic hysteresis loss of core of reactor and the frequency of electric current are similar to proportional relation, so the high-frequency pulse current of 3KHz huge magnetic hysteresis loss of meeting generation in iron core, thereby make the temperature rise of reactor surpass the scope that insulating material can bear.Large power reactor particularly, the design of its cooling system and magnetic circuit and to make be a key that is difficult to capture always.
The utility model content
Technical problem to be solved of the present utility model provides a kind of water-cooled pulsactor, and this water-cooled pulsactor has favorable cooling effect.

A kind of water-cooled pulsactor comprises iron core, coil and cooling device; Described coil winding is on iron core; It is characterized in that described cooling device comprises distributor and a plurality of heat exchanger; Described a plurality of heat exchanger is arranged on the inboard of coil and is close to the iron core setting; Described distributor and a plurality of heat exchanger by cross current to form water cooling labyrinth.
Described coil is 2, and described heat exchanger is 4.
Specifically, heat exchanger is arranged on the inboard (among the figure visible its top and bottom) of coil and is close to the iron core setting, and reactor has 2 coils, be provided with on each coil 2 heat exchangers (each 1 of iron core both sides, as depicted in figs. 1 and 2).4 outlet pipes and 4 return pipes are arranged on the distributor, and each a root outlet pipe and a return pipe and a heat exchanger are connected to form a cooling channel, have 4 cooling channels.Distributor connects external drive mechanism and drives cooling water circulation cycle in cooling channel, realizes the function of cooling coil and iron core.
The beneficial effect of utility model:
The operating current of this water-cooled pulsactor (frequency parameter is 3KHz) can reach 600A, owing to adopted unique cooling device, temperature rise has well solved the cooling problem of 3KHz pulsactor well below the class of insulation of used insulating material.And cooling device is not charged, and the dielectric strength height, is applicable to high-pressure system.
Description of drawings
Fig. 1 is structural representation-front view of embodiment 1.
Fig. 2 is structural representation-end view of embodiment 1.
Wherein: 1-line bank, 2-heat exchanger, 3-iron core, 4-coil, 5-distributor, 6-water pipe head.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1:
As shown in Figure 1, 2, a kind of water-cooled pulsactor comprises iron core 3, coil 4 and cooling device; Described coil winding is on iron core; It is characterized in that described cooling device comprises distributor 5 and a plurality of heat exchanger 2; Described a plurality of heat exchanger 2 is arranged on the inboard (visible its top and bottom among the figure) of coil 4 and is close to iron core 3 and is provided with; Described distributor 5 with a plurality of heat exchangers 2 by cross current to form water cooling labyrinth [water pipe is connected in the water pipe head 6].
Described coil is 2, and described heat exchanger is 4.
Water-cooled 3KHz pulsactor is made up of iron core, coil and cooling system, is installed in the heavy-duty rectifier, cooperates with capacitor to form filter circuit, and the high-frequency impulse that IGBT is exported is converted to direct current.
Iron core by about two posts and up and down two yokes be combined into square frame shape, post and yoke all are that thin silicon steel plates builds up.About coil adopts aluminium strip to be wound on respectively on two posts.Two groups of coils are connected mutually, and it draws the plating of aluminium row terminals from beginning to end with the copper layer.Cooling system is made up of a distributor and 4 heat exchangers, connects with flexible pipe therebetween.Heat exchanger is close to the iron core column both sides.Distributor is close to the iron core bottom, and cooling water is assigned to 4 heat exchangers, itself also plays the effect of cooling iron core simultaneously.Cooling water carries out outer loop through the distributor inflow heat exchanger by importing distributor behind the heat exchanger again, to take away the heat that iron core and coil produce, the reactor temperature rise control in allowed limits.Has good insulation performance between cooler and the coil.
The reactor major parameter is as follows:
Inductance value 200uH;
Maximum unsaturated electric current 1000A (DC);
Pulse frequency 3KHz;
Pulse voltage peak-to-peak value 600V;
Class of insulation H;
Core section 80mm*100mm;
Coil turn 20;
This reactor characteristics:
Be applicable to the 3KHz high-frequency impulse;
Maximum unsaturated electric current can reach 1000A (DC);
Good water-cooling effect is better than air cooling and oil cooling, adopt the H class F insulation, and temperature rise is no more than the B level;
Cooling device is not charged, and the dielectric strength height, is applicable to high-pressure system.
