The utility model has a manual adjustment mode and an automatic adjustment mode to be selected and reduces the weight, the volume and the cost of the apparatus. The utility model has the characteristics of novel design, simple structure, convenient maintenance and strong general purpose and interchange ability.
Description
The utility model is the indoor conventional equipment that is used for 4 volts of acid or 2.5 volts of alkaline mine lamps are carried out constant voltage charge of coal mine ground.
Existing lamp-charging rack generally adopts saturable reactor to do AC voltage adjusting, as KTSB-102 and the KTJB-102 type charging rack that Shanghai Mining Electric Appliance Factory produces, adopts the autotransformer pressure regulation in addition.Its major defect is the variation that needs in charging process according to power supply or load, and manual adjustments is carried out in output to direct current at any time.In addition, owing to adopt large-scale electrical appliance such as reactor, the consumption of copper cash and silicon steel sheet is very big, attached charger outward also sometimes, and these have all increased the weight of equipment, volume and cost, and make the manufacturing process complexity.
The utility model is designed a kind of outer controllable silicon charging rack that is equipped with and can keeps constant voltage charge to mine lamp automatically of setting up that need not in order to overcome the deficiency of existing product.
Technical characterstic of the present utility model is achieved in that
The support body profile made from two-sided three layers of sheet metal is shown in figure one, and indicating device frame (4) and lamp box frame (5) that charge indicator and charging contact element are housed above connect with vertical plates on both sides (3) with securing member.The electric equipments of charging rack is housed in the lower cage (6) that has the heat radiation window.Operation and indicator elments such as voltmeter are equipped with in dodge gate (1) outside, and fallible components such as fuse, card are equipped with in the inside.For by the convenience in dress and the maintenance, outer cover plate (2) and riser (3) are used Bolt Connection in the above, then use clamping plate (9) fixing below, (9) can weld with (3).In addition, lamp box frame (5) is fixed by bolts on the riser after this end of dodge gate is to weld with link stopper, then adopts survivor of a murder attempt's connecting mode to snap on the link stopper (10) that tightens together with riser (3) at the other end.When the equipment of maintenance in the lower cage need be dismantled this lamp box frame, as long as open dodge gate, back out the link stopper fastening bolt, upwards one carry and getting final product then.
Circuit theory of the present utility model is shown in figure two and figure three: single phase alternating current power supply is through fuse 1RD, unit switch K(or A.C. contactor JC), bidirectional triode thyristor KS, primary side to rectifier transformer ZB, the full-wave rectifying circuit that input silicon rectifier cell 1ZG forms after step-down is output as Rectified alternating current.
The height of output voltage is by regulator potentiometer W
1, that is the size of the change KS angle of flow obtains.Triggering ring current is supplied with by unijunction transistor BT, resistance R by control transformer KB, silicon rectification bridge 2ZG
2, R
3, W
1, capacitor C
1The phase shift of the relaxation oscillator control trigger impulse of forming with pulse transformer MB.Potentiometer W
2, Resistor-Capacitor Unit R
6, R
5And C
2The detection loop of forming, the variation of reflection output voltage.
The automatic constant-pressure function is that the closed control circuit that crystal amplifier and relaxation oscillator are formed is finished by the detection loop.When grid ac voltage or charging mine lamp load change and when causing the output dc voltage fluctuation, detect the loop variation of this voltage is added on the emitter junction of transistor BG, after BG amplifies, act on the capacitor C of relaxation oscillator
1Two ends influence R by shadow
3-C
1The loop discharge and recharge time constant, automatically adjust the phase shift that unijunction transistor BT produces pulse triggering signal, that is the angle of flow of change controllable silicon KS, make rectifier transformer ZB primary side alternating voltage produce opposite variation, thereby it is invariable to keep output dc voltage.Suitable regulator potentiometer W
1And W
2, can obtain enough precision of voltage regulations and output voltage adjustable range.
Automatic constant-pressure design objective of the present utility model is:
For the acid miner lamp load, input ac voltage 220V ± 10%, when load current changes the 10-100% be no more than rated value, output dc voltage answers automatic stabilisation at 5 ± 0.1V
For alkaline mine lamp load, input ac voltage 380V ± 10%, when load current changes the 10-100% be no more than rated value, output dc voltage automatic stabilisation is at 3.5 ± 0.1V
Enforcement product of the present utility model has than existing charging rack (charger) that circuit is simple, easy to manufacture, the characteristics of superior performance, and complete machine structure is new, profile is little, cost is low.Only thyristor replaces saturable reactor, and for KTJB-102 type lamp-charging rack (charger), every can reduce cost 564 yuan, in complete set of electric apparatus can both be packed support body in addition, also can save attaching device and connection thereof.

Embodiment
The utility model can adopt manually or regulate two kinds of constant voltage working methods automatically provides selection for the user: when manual adjustments, as long as with the potentiometer W in the printed board
2Being screwed into the end counterclockwise gets final product; When the needs automatic constant-pressure is controlled, at first connect load, with potentiometer W
1And W
2All be threaded to maximum position, then energized is observed voltmeter, counterclockwise turn W
2, a little more than predetermined value, use W again until output voltage
1Transfer to predetermined value and can satisfy instructions for use.
In figure two and figure three, the element in the dashed rectangle is installed on the printed-circuit card plate, and card can exchange.
Charging circuit of the present utility model has very big versatility, utilize its schematic diagram not only can make the seriation lamp-charging rack of different size, can also make the various charging devices that have other storage battery (as automobile storage battery) usefulness of charging structure of the same type with mine lamp.
In addition, owing to adopt bidirectional triode thyristor, make the transformer secondary circuit select the bind mode of halfwave rectifier, full-wave rectification, full-wave rectification or bridge rectifier flexibly for use as required and do not influence the technical performance of its automatic constant-pressure in the AC side pressure regulation.
