Description
Technical field
The utility model relates to a kind of acousto-optic alarm for mineral for switch transmission test.
Background technology
Switch transmission test is that transforming plant protecting prerun, Quan Jian, line outlet such as enable at the very important link in work, is directly connected to the stable operation of electrical network and the safety of personal equipment.In the time carrying out switch transmission test, in order to prevent from accidentally injuring staff, need there is the on-the-spot monitoring of special messenger switch transmission test process.Sometimes because of extraneous factor, there is monitoring risk not in place.Many power equipments are in the time of operation simultaneously, all need to isolate with people, power department is conventionally by setting up the methods such as safety signs board, bracing wire net, luminous lamp to reach warning function, but these methods all belong to passive type warning, can not play good safe warning function, particularly at dense fog, blow, rain etc. under inclement weather, the close together that safety signs board can be observed, safety signs board indicates fuzzy, or wiped off by wind and artificial destruction etc., safety signs board can not play its due effect.Existing safety signs board adopts word, icon mode mostly in addition, and for still poor old man or child of identification capacity, safety signs board performs practically no function, and someone always person is strayed into hazardous location, causes the loss of lives and properties.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of acousto-optic alarm for mineral for switch transmission test.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows:
For an acousto-optic alarm for mineral for switch transmission test, it is characterized in that: it comprises attention device shell, induction and sound alarm circuit and light-operated and optical alarm circuit;
Described induction and sound alarm circuit are made up of current-limiting resistance R1, infrared induction pipe U1 and phonetic warning chip; Described current-limiting resistance R1 connects with the power valve of infrared induction pipe U1, and 4 pin of the receiving tube of described infrared induction pipe U1 are connected with its 1 pin, and its 3 pin connects the negative pole of power supply through phonetic warning chip;
Described light-operated and optical alarm circuit is made up of photoresistance RV, light emitting diode DS1 and resistance R 2-R3; After described resistance R 2 and photoresistance RV connect, between the both positive and negative polarity that is connected on power supply of composition, described resistance R 3 is connected on after connecting with light emitting diode DS1 between resistance R 2 and the node of photoresistance RV and the negative pole of power supply.
The beneficial effect that adopts technique scheme to produce is:
Can greatly improve security, the reliability of transformer substation switch transmission test, and have the advantages that volume is little, Installation and Debugging are easy to use, absorption fixed insulation shell is simpler, efficiently solve the security hidden trouble in switch transmission test, can also promote the use of on other equipment that warning mark need to be installed simultaneously.First improved security, the reliability of transformer substation switch maintenance transmission,
The utility model simple possible, easily manufactured, simple and practical, light emitting diode DS1 and induction and sound alarm circuit low price, can also be generalized on other equipment that warning mark need to be installed.
Brief description of the drawings
Fig. 1 is the circuit theory diagrams of the utility model embodiment 1;
Fig. 2 is the circuit theory diagrams of the utility model embodiment 2;
In figure: 1, phonetic warning chip.
Embodiment
Referring to accompanying drawing 1-2, the structure of a specific embodiment of the utility model comprises:
For an acousto-optic alarm for mineral for switch transmission test, it is characterized in that: it comprises attention device shell, induction and sound alarm circuit and light-operated and optical alarm circuit; Induction and sound alarm circuit are made up of current-limiting resistance R1, infrared induction pipe U1 and phonetic warning chip; Current-limiting resistance R1 connects with the power valve of infrared induction pipe U1, and 4 pin of the receiving tube of infrared induction pipe U1 are connected with its 1 pin, and its 3 pin connects the negative pole of power supply through phonetic warning chip; Light-operated and optical alarm circuit is made up of photoresistance RV, light emitting diode DS1 and resistance R 2-R3; The resistance of photoresistance RV weakens with the enhancing of intensity of illumination, after resistance R 2 and photoresistance RV connect, between the both positive and negative polarity that is connected on power supply of composition, resistance R 3 is connected on after connecting with light emitting diode DS1 between resistance R 2 and the node of photoresistance RV and the negative pole of power supply.
It also comprises switch S 1; Switch S 1 is connected with power supply, and current-limiting resistance R1 is connected between switch S 1 and the negative pole of power supply after connecting with the power valve of infrared induction pipe U1.Attention device shell is insulation crust.
It also comprises and is individually fixed in two blocks of upper and lower strip-shaped permanent-magnet iron that are arranged in parallel in insulation crust.The model of infrared induction pipe U1 is TCRT5000.The model of phonetic warning chip is ISD1110.
Referring to accompanying drawing, principle of work of the present invention is:
Embodiment 1
Referring to accompanying drawing 1, transformer substation switch drive apparatus shell is irony, the insulation crust of the present embodiment is the cubic shell that igelite is made, utilize two blocks of strip-shaped permanent-magnet iron that are arranged in parallel fixing in insulation crust, this attention device is directly adsorbed and is fitted on transformer substation switch drive apparatus shell.Power supply is 3 joint 1.5V electric battery, and phonetic warning chip can shift to an earlier date the voice that typing will be warned as required, the information warning of typing in the present embodiment " switch transmission, please don't be close ".Starting switch S1, in the time having people to enter in induction range (2 meters), the tube-launched infrared ray of infrared induction pipe U1 is accepted pipe and receives, and audio alert module 1 starts and sends the caveat of " switch transmission, please don't be close " that record in advance.If evening, photoresistance RV resistance increases, and it is luminous that light emitting diode DS1 continues conducting, light-operated and optical alarm circuit starts, and reaches the object of warning near personnel, if daytime, photoresistance RV resistance weakens, and light emitting diode DS1 is not luminous, and light-operated and optical alarm circuit disconnects.
