Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of high voltage converter, particularly a kind of busbar structure that is used for high voltage transducer power unit.
Background technology
The high pressure of high voltage converter is to boost by the mode of many groups power unit cascade to reach required high pressure output, so the rated voltage of single power cell output, and required unit number what have just determined.If each unit all reaches maximum with the voltage of output, the number of unit will reduce accordingly so.Simultaneously, the number of power cell can not drop to seldom, otherwise is unfavorable for many level outputs of high voltage converter, increases the harmonic content of global voltage.In case exceeding standard, harmonic content will impact electrical network.Adopt many level mode of power unit cascade structure just to can be good at addressing this problem, for example, adopt the mode of 8 groups or 9 groups units in series in the high voltage converter of 10KV, the direct current supply voltage of each unit reaches 850V to 1000V.Such high pressure initial conditions is to the stability and the very strict requirement of insulating properties proposition of direct current supply; On the other hand, the electrochemical capacitor of importing as direct current is a cascaded structure, and single electrochemical capacitor is bulky.Adopt traditional connected mode; inductance value is big; transient state is by power component insulated gate bipolar power tube (Insulated Gate Bipolar Transistor; abbreviation I GBT) spike that produces will absorb with the absorption electric capacity of special use, otherwise just power component is produced any protective effect.
Summary of the invention
The objective of the invention is to have the problems referred to above at existing technology, proposed a kind of simple in structure, production cost is low, increase the busbar structure that is used for high voltage transducer power unit of direct current supply stability.
Purpose of the present invention can realize by following technical proposal: a kind of busbar structure that is used for high voltage transducer power unit, it is characterized in that, comprise three-layer insulated at least layer and at least two copper polar plates, the two ends of this busbar structure all are set to all be connected with copper polar plate between insulating barrier and the described every two adjacent insulating barriers, described copper polar plate has at least a slice vertically to be provided with, remaining copper polar plate horizontally set.
The quantity of copper polar plate is always lacked one than the quantity of insulating barrier, and the copper polar plate of transverse arrangement of turbo can reach simultaneously increases the capacitance purpose, and the vertical copper polar plate of arranging can be negative terminals lead-in wire.
In above-mentioned a kind of busbar structure that is used for high voltage transducer power unit, fixedly connected between described copper polar plate and the insulating barrier by hot melting mode.It is more firm to make that like this copper polar plate is connected with insulating barrier, can not destroy this body structure of copper polar plate and insulating barrier simultaneously.
In above-mentioned a kind of busbar structure that is used for high voltage transducer power unit, described insulating barrier adopts the insulation polyester material to be made.Because whole busbar structure is withstand voltage and insulation depends primarily on insulating barrier between two copper polar plates, and between two copper polar plates, has only a layer insulating, so the intensity for insulating material has high requirements, the insulating barrier that therefore adopts the insulation polyester material to make is an optimal case.
In above-mentioned a kind of busbar structure that is used for high voltage transducer power unit, described thickness of insulating layer is 3 mils～10 mils.As preferred version, the thickness of insulating barrier is 6 mil the bests.
In above-mentioned a kind of busbar structure that is used for high voltage transducer power unit, described insulating barrier has four layers, and described copper polar plate has three.Can avoid volume excessive so that the busbar structure is compact like this, thereby make that taking up room of this busbar structure is little.
Compared with prior art, originally the busbar structure that is used for high voltage transducer power unit is utilized copper polar plate and insulating barrier interlaced arrangement, both sides are provided with insulating barrier, the spike that can absorbed power element I GBT transient state produces, use special absorption electric capacity thereby save, reduce the manufacturing cost of whole device, the copper polar plate of copper polar plate transverse arrangement of turbo can increase capacitance simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure, 1, insulating barrier; 2, copper polar plate.
Embodiment
Below be specific embodiments of the invention and in conjunction with the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiment.
As shown in Figure 1, the busbar structure that originally is used for high voltage transducer power unit comprises insulating barrier and at least two copper polar plates 2 of at least three layers, and wherein the two ends of this busbar structure all are arranged as insulating barrier 1.
Copper polar plate 2 and insulating barrier 1 interlaced arrangement that is to say between every two adjacent insulating barriers 1 all to be connected with copper polar plate 2 that the quantity of copper polar plate 2 is always lacked one than the quantity of insulating barrier 1.In the present embodiment, insulating barrier 1 has four layers, and copper polar plate 2 has three, can avoid volume excessive so that the busbar structure is compact like this, thereby make that taking up room of this busbar structure is little.Fixedly connected by hot melting mode between copper polar plate 2 and the insulating barrier 1, it is more firm to make that like this copper polar plate 2 is connected with insulating barrier 1, can not destroy this body structure of copper polar plate 2 and insulating barrier 1 simultaneously.Copper polar plate 2 has a slice vertically to be provided with, remaining two copper polar plate 2 horizontally set.The copper polar plate 2 of transverse arrangement of turbo can reach increases the capacitance purpose, and the vertical copper polar plate of arranging 2 can be negative terminals lead-in wire.
Because whole busbar structure is withstand voltage and insulation depends primarily on insulating barrier 1 between the copper polar plate 2, and has only a layer insulating 1 between copper polar plate 2, so have high requirements for the intensity of insulating material.Therefore the material of insulating barrier 1 adopts the insulation polyester material, and the thickness of insulating barrier 1 is 3 mils～10 mils simultaneously, and in the present embodiment, as preferred version, the thickness of insulating barrier is 6 mil the bests.
As shown in Figure 2, when adopting two copper polar plates 2, a slice copper polar plate 2 transverse arrangement of turbo wherein, another sheet copper polar plate 2 is vertically arranged.The copper polar plate 2 of transverse arrangement of turbo can reach increases the capacitance purpose, and the vertical copper polar plate of arranging 2 can be negative terminals lead-in wire.
This busbar structure provides direct voltage source for the outside, and in use, the insulating barrier 1 of busbar structure one end connects in the rectifier bridge, and the insulating barrier 1 of the other end connects electric capacity, and electric capacity is connected on the power component again.Both stray inductance can be reduced after adopting this busbar structure, long-pending attached electric capacity can be increased again.Can just can work by any absorption electric capacity for the spike that is produced by power component IGBT like this, thereby reduce cost.
Specific embodiment described herein only is that the present invention's spirit is illustrated.The technical staff of the technical field of the invention can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
