Description

The mining energy-saving explosion-proof lamp

The utility model relates to the improvement of mine anti-explosion lamp, specifically a kind of mining energy-saving explosion-proof lamp that is applicable in 127 ± 20 volts of voltage ranges.

At present; mine anti-explosion lamp in 127 ± 20 volts of voltage ranges using; bulb, bulb plug, base, suspension ring, protecting glass, metal coating net by 127 volts of 60W constitute; this explosion-proof lamp exists the caloric value height, shortcomings such as power consumption is big, service life is short, change often, cost of manufacture height.

The purpose of this utility model be to provide a kind of be applicable in 127 ± 20 volts of voltage ranges have that caloric value is low, power consumption is little, light efficiency is high, long service life, mining energy-saving explosion-proof lamp that cost of manufacture is low.

The utility model is achieved in that this mining energy-saving explosion-proof lamp is made of fluorescent tube, tube plug, base, suspension ring, protecting glass, metal coating net; its fluorescent tube adopts " U " shape power saving fluorescent lamps; " U " shape power saving fluorescent lamps is connected on the output of 127V ballast, and 127V ballast power input is welded on the tube plug.The 127V ballast is contained in the annular gold, is tube plug in the centre of ring box; Its " U " shape power saving fluorescent lamps can be established 2-3, can install side by side in the time of 2, but triangularity is installed in the time of 3, and when two " U " shape power saving fluorescent lamps were installed, its power was 9 watts, when three " U " shape power saving fluorescent lamps are installed, its power is 13 watts, after " U " shape power saving fluorescent lamps and 127V ballast are assembled, goes up and is being equipped with on the base of lamp tube socket, buckle protecting glass and sealing, again the metal coating net is fixed on the base and can installs with gim peg; The 127V ballast suppresses circuit, power circuit, power factor by short-circuit protection and harmonic wave to be adjusted circuit, self-maintained circuit, tube circuit and constitutes, and resistance is the field-discharge resistance RT of 8-51 Ω and the coil L of 1-100mH ₁Be connected on and form short-circuit protection and harmonic wave inhibition circuit in the power circuit,, then work as the Q in the self-maintained circuit if its role is to there is not short-circuit protection circuit ₁, Q ₂During breakdown or overcurrent, the electric current of power circuit can be very big, often causes gas and dust explosion, perhaps causes underground electric network to damage, because increased short-circuit protection circuit, works as Q because of strong pulse ₁, Q ₂During breakdown or overcurrent, the resistance of field-discharge resistance RT is tending towards ∞, just cuts off the electricity supply, and has avoided the generation of spark, has so just protected underground electric network, has avoided the burning things which may cause a fire disaster of gas accident, and after strong pulse, the RT resistance returns to initial value again.Owing to increased the harmonic wave inhibition, made the 127V ballast circuit be reduced to national standard to the electric network pollution degree.Choose the inductance L of self-maintained circuit ₄, L ₅, capacitor C ₁, C ₂, C ₃, resistance R ₁With the resonant capacitance C in the tube circuit ₄And mutual inductance L ₁: L ₂: L ₃Value, make its circuit adapt to 127 ± 20 volts of voltage power supply environment in down-hole, its value L ₄, L ₅Composite value be 60-150mH, C ₄Be 400V 4700-10000P, can be normally luminous under 127 ± 20 volts of voltages with the assurance fluorescent tube, and the service life of prolongation " U " shape power saving fluorescent lamps, C in self-maintained circuit ₁Value be 400V 1000-3300P, C ₂, C ₃Be 400V 22n, its mutual inductance L ₂: L ₃: L ₄=3: 3: 7.

The utility model has the advantages that: compare with the mine anti-explosion lamp of present use, caloric value is low, power consumption is few, light efficiency is high, long service life, and reasonable in design, stable performance, and cost of manufacture is low.
