Abstract
The utility model provides a kind of du/dt wave filters, including horizontal reactors, and binding post is fixed on the front upper place of the horizontal reactors by support；Filter condenser is on pcb board, and pcb board is fixed on the back upper place of the horizontal reactors by support；Aluminum-housed resistor is fixed on the top of the horizontal reactors by support.The part of binding post exceeds the front edge of the horizontal reactors.The utility model has greatly reduced the space stretched out in front of reactor, has been that other components such as contactor leave installing space by selecting aluminum-housed resistor to improve the position of binding post.The capacitor box of original embedding electric capacity is made into monolithic pcb board, and electric capacity is welded on pcb board, pcb board is vertically placed on to reactor back upper place simultaneously, and away from resistor, both influence of the resistor high temperature to electric capacity had been reduced, the thermal diffusivity of itself is also improved, the stability, reliability and security of wave filter is improved.
Description
Technical field
The utility model is related to a kind of du/dt wave filters, for Small-power Inverter outlet side, belongs to passive filter knot
Structure design field.
Background technology
As shown in figure 1, traditional du/dt wave filters it is general by horizontal reactors 1, ripple resistor 2, embedding capacitor box 3,
Binding post 4, first support 5, second support 6 are constituted.Binding post 4 is fixed on before horizontal reactors 1 by first support 5
Side, embedding capacitor box 3 and ripple resistor 2 are all fixed in the second support 6 directly over horizontal reactors 1.
Above-mentioned traditional du/dt wave filters use ripple resistance, and for the ease of patching operations, binding post must stretch out electricity
Anti- device front end.When wall hanging is installed, space-consuming is big, causes the interference with other devices.Electric capacity is generally potted in capacitor box,
Near resistor, resistor temperature higher when working is adversely affected to electric capacity heat-radiation belt, greatly reduces electric capacity
Reliability.
Utility model content
The technical problems to be solved in the utility model is the influence for how reducing resistor high temperature to electric capacity, improves wave filter
Stability and reliability.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is to provide a kind of du/dt wave filters, including sleeping
Formula reactor, it is characterised in that：Binding post is fixed on the front upper place of the horizontal reactors by support；Filter condenser is set
In on pcb board, pcb board is fixed on the back upper place of the horizontal reactors by support；Aluminum-housed resistor is fixed on by support
The top of the horizontal reactors.
Preferably, the part of the binding post exceeds the front edge of the horizontal reactors.
Preferably, the pcb board is vertically fixed on the back upper place of the horizontal reactors.
Preferably, the bottom of the aluminum-housed resistor is provided with insulation board.
Preferably, the aluminum-housed resistor is located at the top of binding post and filter condenser.
The utility model has greatly reduced stretching reactor by selecting aluminum-housed resistor to improve the position of binding post
The space in front, is that other components such as contactor leave installing space.The capacitor box of original embedding electric capacity is made into list
Block pcb board, and electric capacity is welded on pcb board.Pcb board is vertically placed on to reactor back upper place, and remote resistor simultaneously, both
Influence of the resistor high temperature to electric capacity is reduced, the thermal diffusivity of itself is also improved.Condenser welding connected on pcb board it is more reliable,
Safety.
The device that the utility model is provided overcomes the deficiencies in the prior art, and thermal diffusivity is good, greatly reduces resistor high
Influence of the temperature to electric capacity, while it is that other components reserve more spaces in front of reactor to make, improves the stabilization of wave filter
Property, reliability and security.
Brief description of the drawings
Fig. 1 is traditional du/dt filter construction schematic diagrames；
The du/dt filter construction schematic diagrames that Fig. 2 provides for the present embodiment.
Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation scope of the present utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
The du/dt filter construction schematic diagrames that Fig. 1 provides for the present embodiment, described du/dt wave filters are by horizontal reactance
Device 1, aluminum-housed resistor 7, filter condenser 8, pcb board 9, binding post 4, first support 5, second support 6,10 groups of insulation board
Into.Binding post 4 is fixed on the front upper place of horizontal reactors 1 by first support 5.Filter condenser 8 is welded on pcb board 9,
Pcb board 9 is vertically fixed on the back upper place of horizontal reactors 1 by second support 6.Aluminum-housed resistor 7 is individually solid by second support 6
It is scheduled on top.
The top of second support 6 is fixed with insulation board 10, and aluminum-housed resistor 7 is located on insulation board 10.
Some exceeds the front of horizontal reactors 1 with binding post 4, saves the anterior installing space of horizontal reactors 1.
The du/dt filter constructions that the present embodiment is provided have greatly reduced the space of the front wiring position of horizontal reactors 1,
The pcb board 9 for being fixed with filter condenser 8 is vertically placed on the back upper place of horizontal reactors 1, and remote aluminum-housed resistor 7 simultaneously, both
Influence of the high temperature of aluminum-housed resistor 7 to filter condenser 8 is reduced, the thermal diffusivity of itself is also improved.Filter condenser 8 is welded in
On pcb board 9, connect more reliable, safety.
