Abstract
The utility model relates to a blasting machine used for engineering explosion and particularly well drilling explosion. The utility model uses the alternating current as the power supply, and the blasting machine is composed of a transformer, a rectifier, a capacitor, an electronic switch, etc. The utility model is characterized in that when in blasting a blasting switch turns on the trigger circuit of the electronic switch the electricity of the capacitor and the load form a blasting current loop through the electronic switch. Because no contact is arranged in the circuit, the allowing current is large, so the non-blasting problem of the well parallel circuit and the problem of the short service life of the blasting machine and anti-explosion caused by the high-voltage spark generated by the contacts are solved.
Description
The electric cap usefulness of detonating when the utility model is mainly used in engineering explosion belongs to the utensil that detonates.
At present the exploder of usefulness, with transistor type for the most general, its cardinal principle is, with the dc battery is power supply, become pulse voltage through the transistor oscillating circuit, boost, diode rectification, charge through transformer to capacitor, press (turning) mechanical type ms switch after the charging and discharge, ignite electric cap to electric cap.The shortcoming of this exploder is, it is mechanical blowing out switch because of employing, and by two contacting circuit, therefore the electric current of the blowing out contact of will all flowing through allows initiation current low, and the detonator that can only be used for series circuit is all risen quick-fried; Two contacts are at energising moment generation high tension spark when detonating in addition, and this is definitely unallowed under coal mine, so require shell explosion-proof; And the contact burns out the life-span weak point easily.In shaft of vertical well driving because the particular surroundings of down-hole, electric cap adopts parallel way more, present exploder can not be applicable to that vertical blows out, so generally can only adopt the common A.C. current of industrial 220V or 380V directly blows out, but because of the effective detonation of voltage alternating dashes can be limited, so easily produce blown-out shot, influence demolition effect, handle trouble.
The purpose of this utility model, provide and a kind ofly do power supply with alternating current, the exploder of non-contact type electronic switch, not only can be used for connecting blowing out but also being used for parallel connection (or mixing connection) and blow out, thereby solve the blown-out shot problem that vertical tunnels or Other Engineering is directly blown out with alternating current and produce; Another purpose is to solve because of contact generation high tension spark, the burning of contact of bringing and downhole safety problem.
The technical solution of the utility model is: a box-type shell is arranged, and the panel front in the shell is equipped with blows out binding post, voltage indicator, charge switch and the switch of blowing out; The electric elements that wiring board arranged in the shell and connect in the circuit board, electric elements have transformer, rectifier, charging capacitor, electronic switching tube and resistance etc.Its connecting mode is: 1, step-up transformer primary coil one end is directly connect electric power incoming line, the other end connects another inlet wire of power supply by the charge switch on the panel; 2, step-up transformer secondary coil two ends are connected upward rectifier, charging capacitor, current-limiting resistance, form R-C rectification charging loop; 3, the voltage indicator on charge circuit two ends and the panel and connecing; 4, the positive pole of charge circuit is connected on blowing out on the binding post (+) on the panel, the negative pole of charge circuit connects the positive pole of electronic switch, the negative pole of electronic switch is connected on another binding post (-) on the panel again, forms with load (detonator) and blows out current loop; 5, the trigger electrode of electronic switch contacts positive source by blowing out on the panel behind the switch, triggers power cathode and connects the electronic switch positive pole, forms the triggering electric power loop of electronic switch.
Its operation principle is, opening charge switch and 220V AC power connects, rectifier rectification is a pulse direct current to the charging capacitor energy storage of charging after step-up transformer boosts, charge indicator shows magnitude of voltage at any time, after charging reaches certain voltage, opens and blows out switch, trigger power supply and make the electronic switch conducting, the circuit of blowing out this moment is connected, and capacitor discharges to detonator, ignites electric cap.
The utility model is blown out particularly the vertical driving for engineering and is blown out a kind of contactless electronic beam switch exploder is provided, solved and in the past the sort ofly directly blown out the blown-out shot phenomenon that produces, and solved the explosion-proof problem that blaster contact easy burn-out and high tension spark bring with alternating current.
