Abstract
The utility model relates to a kind of power panel; particularly relate to a kind of improved electric source plate; comprise power panel, output connection seat; output connection seat is fixed on power supply panel seat; also comprise overvoltage protection; overvoltage protection is arranged on power panel outside, and is connected with output connection seat by wire, is provided with arc-extinguish chamber between overvoltage protection and power supply panel seat.The utility model improved electric source plate separates overvoltage protection and power supply panel seat, places separately, is connected by wire; when overvoltage, overvoltage protection action, can not have influence on other parts on power supply panel seat because of the hard arc produced during action; reduce the loss, simple.
Description
Technical field
The utility model relates to a kind of power panel, particularly relates to a kind of improved electric source apparatus.
Background technology
The electrical equipment control of Ba Mage spinning drawing equipment is powered and is adopted 500V direct current common bus to power; this kind of supply power mode has individual drawback; exactly once in loop certain equipment short circuit the voltage instantaneous in whole loop can be caused to increase; cause the overvoltage protection on equipment and piezo-resistance action; cause fusible core protection act, other elements on All other routes plate can be protected like this to be without prejudice.But Ba Mage does not carry out independent design the overvoltage protection of measuring pump variable-frequency electric source plate and up-coiler power panel when designing, but direct and on power panel point of incoming cables (as shown in Figure 1), overvoltage protection 30 is directly connected with output connection seat 20, and be arranged on power supply panel seat 10, once piezo-resistance plays action, although protect element not damage, but the hard arc that action causes can cause again whole power panel all to damage, lost value is at least more than 20,000 yuan, if electric arc greatly also can have influence on other circuit board, loss more strengthens, can more than 50,000 yuan.
Utility model content
The purpose of this utility model is to provide a kind of improved electric source apparatus, makes the miscellaneous part that can not affect during piezo-resistance action protection in supply unit, reasonable in design, simple.
For achieving the above object; the technical scheme that the utility model adopts is: a kind of improved electric source apparatus; comprise power supply panel seat, output connection seat; output connection seat is fixed on power supply panel seat; described improved electric source apparatus also comprises overvoltage protection; it is outside that overvoltage protection is arranged on power supply panel seat, and be connected with output connection seat by wire, is provided with arc-extinguish chamber between overvoltage protection and power supply panel seat.
Technique scheme, described overvoltage protection is in parallel with output connection seat.
Technique scheme, described overvoltage protection is composed in parallel by multiple piezo-resistance.
Technique scheme, the material of described arc-extinguish chamber is the one of asbestos cement, potter's clay, pottery or BMC.
After adopting technique scheme, the utility model has following good effect:
(1) the utility model improved electric source apparatus separates overvoltage protection and power supply panel seat, places separately, is connected by wire, when overvoltage, overvoltage protection action, can not have influence on other parts on power socket, reduce the loss because of the hard arc produced during action;
(2) the utility model is provided with arc-extinguish chamber between power supply panel seat and overvoltage protection; arc temperature can be reduced; accelerate arc extinction; protection for the parts on power supply panel seat is significant, rational in infrastructure, designs ingenious; cost is low; simple, there is higher practical value, easy to utilize.
Accompanying drawing explanation
Fig. 1 is for improving front power panel structural representation;
Fig. 2 is improved electric source device structure schematic diagram of the present utility model;
Wherein: 1, power supply panel seat, 2, output connection seat, 3, overvoltage protection, 4, arc-extinguish chamber.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 2; for improved electric source apparatus of the present utility model; comprise power supply panel seat 1, output connection seat 2; output connection seat 2 is fixed on power supply panel seat 1; also comprise overvoltage protection 3, it is outside that overvoltage protection 3 is arranged on power supply panel seat 1, and be connected with output connection seat 2 by wire; be provided with arc-extinguish chamber 4 between overvoltage protection 3 and power supply panel seat 1, can stop and eliminate overvoltage protection 3 produce hard arc.
In a specific embodiment, overvoltage protection 3 is in parallel with output connection seat 2, and form discharge loop, overvoltage protection 3 is composed in parallel by multiple piezo-resistance.Arc-extinguish chamber 4 can fixedly mount with overvoltage protection 3, can also fixedly mount with power supply panel seat 1, can produce effect as long as be arranged between overvoltage protection 3 and power supply panel seat 1.The material of arc-extinguish chamber 4 is BMC, therefore plants material by can not because of thermal deformation during high arc temperature effect, and good insulation preformance, the high and easily processing and manufacturing of mechanical strength.
In above-described embodiment, the material of arc-extinguish chamber 4 can also be asbestos cement, potter's clay, pottery any one, all can reach effect the same with team shape moulding compound.
When the utility model uses, direct current or the alternating voltage at improved electric source apparatus two ends lower than nominal voltage, normally should work; When the direct current at improved electric source apparatus two ends or alternating voltage exceed maximum restriction magnitude of voltage; there is action in overvoltage protection 3; parts on protection power source panel seat 1; and because overvoltage protection 3 and power supply panel seat 1 are placed separately; centre is placed with arc-extinguish chamber 4; the hard arc avoided because producing when protection act occurs affects other circuit elements on power supply panel seat 1, reduces unnecessary loss.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection range that the utility model requires.
