Description
Technical field
The utility model is related to switch power technology field, particularly a kind of Portable DC mains case.
Background technology
Permanent magnet mechanism is the structure that a kind of electromagnet actuating permanent magnetism is kept, and due to the presence of permanent magnets N pole, S poles, is determined
Operation power must be DC power supply.And as the department that uses of permanent-magnet breaker, a kind of power transformation operation at the scene is needed to safeguard
In the process, miniaturized and portable continuous-current plant.Conjunction divides during being mainly used in the operation and maintenance of permanent-magnet breaker scene
Lock operates, while can also be used as other temporary sources and use.
Direct-current power supply generally has two kinds of modes 1, accumulator 2, silicon rectifier.
(1) accumulator must be mounted in direct current cabinet since volume is big, and project cost is high.
(2) silicon rectifier is unstable due to bigger by electric network influencing.
But it is existing all to use silicon rectifier, but due to bigger by electric network influencing, out-put supply characteristic is unstable, sometimes
Output capacity is inadequate, often can not be completed the on/off switch operation of permanent-magnet breaker, while is often damaged by electric network influencing component
The shortcomings of.
Utility model content
The purpose of this utility model is that solving more than the deficiencies in the prior art, a kind of Portable DC mains case is provided,
Realize small, light weight, stable working state, portable effect.
In order to achieve the above object, provide following technical scheme：
Portable DC mains case, including babinet, handle, plug, capacitance, the first mast, the second mast and castor,
The handle is placed in babinet upper end, and the castor is placed in babinet lower end, and the plug is placed on rear side of babinet, and the cabinet front has
Cabinet door, first mast, the second mast and capacitance are placed in box house, and first mast and the second mast are put
In capacitance front end, and close to cabinet door, first mast is placed in above the second mast, includes turning on first mast
It changes switch, indicator light, button, be spaced apart and current-limiting resistance, wire-threading device and power module are included on second mast.
Preferably, the power module is connected with current-limiting resistance, and the current-limiting resistance is connected with capacitance.
Preferably, the capacitance point two rows are evenly distributed on the bottom plate of babinet.
The beneficial effects of the utility model are：Handle is placed in babinet upper end, and the structure that castor is placed in babinet lower end realizes electricity
Source case it is portable, be connected by power module with current-limiting resistance, current-limiting resistance be connected with capacitance realize power supply box stabilization work
Make, while the power supply box of present design is small, light weight.
Description of the drawings
Fig. 1 is power supply box overall structure diagram；
Fig. 2 is power supply box internal structure schematic diagram.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing.
Portable DC mains case as depicted in figs. 1 and 2, including babinet 600, handle 400, plug 300, capacitance 200,
First mast 102, the second mast 101 and castor 500, handle 400 are placed in 600 upper end of babinet, and castor 500 is placed in babinet
600 lower ends, plug 300 are placed in 600 rear side of babinet, and there are cabinet door, the first mast 102, the second mast 101 in 600 front side of babinet
It is placed in inside babinet 600 with capacitance 200, the first mast 102 and the second mast 101 are placed in 200 front end of capacitance, and close to cabinet
Door, the first mast 102 are placed in 101 top of the second mast, include change-over switch 120, indicator light on the first mast 102
170th, button 130, be spaced apart 140 and current-limiting resistance 150, wire-threading device 110 and power module 160 are included on the second mast 101.
Wherein, power module 160 is connected with current-limiting resistance 150, and current-limiting resistance 150 is connected with capacitance 200, and capacitance 200 divides
Two rows are evenly distributed on the bottom plate of babinet 600.
Power module 160 is charged by current-limiting resistance 150 to capacitance 200, and capacitance 200 is equivalent to accumulator and plays storage electricity
The function of amount.When needing to close a floodgate, capacitance 200 is made to discharge by button 130 and give mechanism closing coil, be allowed to close a floodgate, needed point
During lock, otherwise capacitance 200 discharges to switching winding, it is allowed to separating brake.Other operation powers are extended to simultaneously to use.
