Abstract
The utility model relates to a conducting type exploder with a testing device. A testing device is composed of a power supply, a conducting resistor, a testing signal input resistor, a current limiting resistor, a display lamp, etc. The exploder is composed of a charging voltage stabilizing device and a blaster, wherein, the charging voltage stabilizing device is formed by connecting a voltage dividing resistor R< 3 >, a W, a neon bulb ND, capacitors C< 8 >, C< 9 >, and transistors BG< 1 >, BG< 2 >. The blaster is composed of a push-pull type current transformer, a voltage doubling rectifying circuit and main capacitors C < 1 > to C < 5 >. The utility model has the advantages of simple structure, convenient use, sensitive and accurate display, safety, small size and light weight, and can satisfy the safety blasting requirements of mining industry, especially coal mines having methane (methane).
Description
The utility model belongs to the design and the manufacturing technology field of the used exploder of mining industry, and it is applicable to the safe detonation electric cap.
Current, as at home and abroad to use in the mining all kinds of exploders generally have only the detonating primer device.Because can not measuring, exploder blows out the opening circuit and the connection situation at detonator networking of bus; when charging, exploder do not have overvoltage protection; the overvoltage that causes charging damages components and parts, can't guarantee to export rated current when igniting and miso-fire occurs, causes accidents such as gas and coal-dust explosion to take place.
At the defective of existing exploder, the purpose of this utility model provides a kind ofly can measure the connection situation of bus of blowing out, and has the conduction type exploder of charging and voltage stabilizing device.
Shell of the present utility model is rectangular boxlike.Adopt the hot pressing of high strength phenolic aldehyde glass fiber to form.Leave Lead-through terminal, conducting observation window, charging and voltage stabilizing observation window and switch key hole on the shell.
The utility model is made of testing arrangement and exploder two parts.The former is a test cell, and the latter is made of stable-pressure device and two unit of trigger.
First module is a testing arrangement, its structure such as Fig. 1, shown in Figure 3, and it is by power supply, current-limiting resistance R
6, R
7Show luminous tube and Lead-through terminal composition with test.
This unit be used for detonator inspection, blow out the inspection of bus connection situation, can prevent miso-fire and the caused explosion accident of line broken circuit.
Second and third unit is stable-pressure device and trigger, its structure as shown in Figure 2, its line construction is as shown in Figure 3.
Unit second is by charging and voltage stabilizing device, divider resistance R
3, W, neon bulb ND, capacitor C
8, C
9, triode BG
1, BG
2Connection forms.
The course of work of this unit is: when trigger charges to rated voltage, by divider resistance R
3, W, neon bulb ND, capacitor C
8, C
9, triode BG
1, BG
2One signal voltage is provided, amplifies locking GB through difference
3Oscillation circuit.Current transformer does not recharge, and prevents main capacitance and other components and parts over-voltage breakdown.And when charging voltage descends, R
3, the signal voltage deficiency that provides of W, neon bulb ND is so that triode BG
1, BG
2Conducting, current transformer continues charging, makes exploder guarantee that stable voltage is arranged, and damages components and parts to guarantee its safe detonation and to prevent because of the charging overvoltage.
Unit the 3rd trigger is by push-pull converter, letter voltage rectifier and main capacitance C
2-C
5Constitute.Its course of work is:
When switch placed " charging " position, current transformer was connected power supply.Starting oscillation, the high pressure of transformer secondary coil output is through diode D
1-D
4Behind the voltage multiplying rectifier, give main capacitance-electrolytic capacitor C
2-C
4Charging.When voltage reached rated value, accurate quick-fried lamp ND was luminous.Go to switch " blowing out " position and then can ignite electric cap this moment.
The utility model can be made different series of products by firing capability (detonating primer quantity: 50,100,150,200) as required, as long as change relevant elements quantity and specification (referring to subordinate list) in the circuit, and need not change structure.
The utility model meets GB3836,1-83 " the explosive atmosphere general requirement of electric apparatus for explosive atmospheres flameproof electrical apparatus ", GB3836,4-83 " the explosion environment general requirement of electric apparatus for explosive atmospheres " and GB7958-87 " the colliery relevant requirements of capacitor blasting machine " and multinomial specification requirement.
The utility model has the advantages that structure is ingenious, easy to use, show sensitive and accurate, safe and reliable; Volume is little, and is in light weight, and cost is low, can satisfy mining industry, and safety fire cracker requirement in the colliery of methane (gas) is particularly arranged.
