Abstract
A power supply informer device of closing the experimental switch consists of a shell, a tailgate, and a control board. The upper part of the front plate of the shell is provided with two red indicating lamps of the light emitting diode with high brightness. The lower part of the front plate of the shell is provided with a loudspeaker. The tailgate is provided with a 36V/18V power transformer and a main control panel. The control board includes a rectifier, a filter, and a voltage regulator circuit, a harmonic shocking circuit without steady-state, a language module and a power amplifier circuit. The utility model applies for the 380V-660V power supply informer device of closing the switch. When the experimental switch is closed to supply power, the utility model gives off a sound-light alarm reminding the operators of that the experimental switch is closed and the power is supplied, avoiding electric contact or the short blaster of the switch and other accidents.
Description
Technical field
Alarm set when the utility model relates to a kind of 380V～660V vacuum magnetic starter power transmission debugging, the informer that specifically a kind of test switch closes a floodgate and reminds operating personnel to note when sending electricity.
Background technology
High and low pressure feeding switch in the colliery, in magnetic starter maintenance and the debugging, when 1140V～6000V high-voltage explosion-proof feeding switch power transmission debugging, all by the staff who enriches working experience is for many years arranged, in strict accordance with work ticket examination and approval system normal operations, and accomplish one man operation one people monitoring; In 380V～660V vacuum magnetic starter power transmission debugging, because the particularity of industry, the colliery worker in varying degrees, situations such as the personnel that exist are assorted, culture is low, in energization test, careless slightly meeting appearance electric leakage is wounded, phenomenon is blown out in the switch short circuit, easily causes the accident.
Summary of the invention
The purpose of this utility model just provides a kind of test switch combined floodgate and send electricity warning device, can give warning in advance, and the accident that effectively prevents takes place, and impels the voice prompting device of staff's standard operation.
The utility model is achieved in that the test switch combined floodgate of being made up of shell, backboard, control board send electricity warning device, main points are: control board is provided with rectification, filtering, voltage stabilizing circuit, no stable state multi resonant oscillating circuit, language module and power amplification circuit, be provided with two high brightness LED red leds on the top of housing front panel, loud speaker is established in the bottom, establishes power transformer and the master board of 36V/18V on backboard.Whenever test switch closes a floodgate when sending electricity, its inner AC660V (380V)/AC36V power transformer gets electric, and the 36V power supply is just sent in the informer, and control board gets electric work, send approximately once/second oscillator signal, make two indicator lights alternately send dazzling ruddiness; Voice module sends speech signal and promotes loud speaker send melodious prompting after power amplification.
Operation principle
Test switch closes behind the isolating switch, its power transformer secondary side just can be exported AC36V voltage, after this voltage is delivered to the Working transformer of informer, again AC36V voltage is become AC18V voltage, deliver to the input of rectifier, the AC18V power supply is through links such as over commutation, filtering, voltage stabilizings, export stable 12V direct voltage, this voltage is supplied with the astable multivibrator of being made up of NE555, the output of its 3 pin approximately once/second the rectangular wave oscillator signal, carry out the luminous indication of replacing of two light-emitting diodes for indicator light; Another road directly promotes loud speaker and sends the sound after language module, power amplification.
The utility model is used for 380V～660V test switch combined floodgate and send electricity warning device, when the test switch combined floodgate send electricity, send sound, light is reported to the police, and reminds operating personnel's test switch to close a floodgate and send electricity, has avoided electric shock or switch short circuit the generation of accident such as to blow out effectively.
Description of drawings
Accompanying drawing is the utility model circuit theory diagrams.
Embodiment
At first, make the shell of a rear portion opened with the steel plate that 2mm is thick, the tapping of backboard flanging, be connected with the front portion with ￠ 4mm bolt, two ￠ 8.5mm holes are bored in the bottom, are fastened on the last wire connection cavity cover plate of test switch, upper position at the housing front panel is installed two high brightness LED red leds, a ￠ 100mm loud speaker is installed in the bottom, gets out gradually to the hole of outdiffusion at the loud speaker center position, helps the propagation of sound; The power transformer and the master board of on the plate of back, a 36V/18V being installed.Wherein, comprise rectification, filtering, voltage stabilizing circuit, no stable state multi resonant oscillating circuit, language module and power amplification circuit on the control board.When the test switch combined floodgate sent electricity, its inner AC660V (380V)/AC36V power transformer got electric, and the 36V power supply is just sent in the informer, and control board gets electric work, sends about 1 time/second oscillator signal, makes two indicator lights alternately send dazzling ruddiness; Voice module sends speech signal and promotes loud speaker send melodious " switch closes a floodgate, and asks the staff to note " sound after power amplification.In time remind operating personnel, " test switch has closed a floodgate and sent " asked normal operations, taken care, and like this, just played the effect that gives warning in advance, and avoided the generation of accident effectively.Therefore, the utlity model has simple in structure, characteristics such as security warning is effective.
