Abstract

This invention pertains to cattle breeding and can be used for livestock heating, including poultry, by means of infrared radiation.The essence of this invention is that in certain equipment containing groups of infrared and erythemal light bulbs connected to the three-phase four-conductor power supply network at the infrared light bulb Y-connection to the uniform load phases, the infrared light bulbs are connected to the three-phase four-conductor power supply network without one phase and with disconnected neutral conductor in such a way that an irregularly distributed phase load is created, while the erythemal light bulbs are connected to the electric potential induced by the neutral point bias in this electric circuit. Additionally, a switch is connected parallel to the erythemal light bulbs, while a connecting circuit is arranged between the zero-points of the infrared light bulb equipment by means of a switch. Furthermore, a metal electrode is attached to the surface of the glass tubes of the erythemal light bulbs and connected to a zero-point of the power supply network.<IMAGE>

Description

The invention relates to the livestock industry and can be applied to infrared heating and ultraviolet irradiation of farm animals. Equally, the invention can also be used in poultry farming.

A livestock irradiation apparatus of the type ЭО-1-ЗОМ is known, which contains an erythrometer bulb, an incandescent lamp and a filament transformer [1].

However, infrared heating of the animals is not possible with this device as the incandescent bulb contained therein is used only as a ballast impedance. In addition, the above-mentioned electrode-heating incandescent transformer is required to ignite the erythema lamp, which complicates and increases the cost of the device.

Closer to the invention is an infrared heating and ultraviolet irradiation apparatus [2] (prototype) for animals of type ИКУФ-1 consisting of an infrared light bulb, which is connected to a three-phase four-wire mains connected to line voltage.

However, the high ballast capacitance of this unit and the special lowering transformer also create a complex electrical circuit and, in addition, result in significant power losses.

The object of the invention is to simplify the electrical circuitry of the apparatus and to achieve energy savings.

The objective is achieved by connecting the infrared light bulbs to a three-phase four-wire power supply without a single phase and terminating the neutral conductor with uneven phase load, while the erythrometer light bulbs are connected to the neutral shear voltage called in this circuit. The figure shows the circuit diagram of the electrical circuit elements of the machine.

The scheme is as follows.

Connecting the infrared lamps 4 and 10 with different rated wattages of phases a and b creates an uneven load producing a neutral shear voltage corresponding to the ignition voltage of the erythrometer lamps. After ignition, the neutral voltage drops to the operating voltage of the erythema lamp. This eliminates the need to use a dimmer transformer.

The required current limitation in the circuit between points 0 and 0 'is provided by the stability of the geometric sum of the known phase currents at a certain degree of asymmetry of the three-phase load. This makes it possible to avoid the use of current limiting ballast chokes in this circuit.

In order to improve the ignition conditions of the light bulb 5 from the starter 3, an aluminum foil electrode 9 is attached to the glass body of the tube, which in turn is connected to the protective ground conductor 8.

They are connected to a separate mains protective earth conductor 8 to prevent the possibility of hazardous touch voltages forming on non-conductive metal parts of the equipment.

The scheme works as follows.

With switches 1,6,7 and 11 in the closed position and switch 2 in the unlocked position, a combined infrared heating and ultraviolet irradiation mode is achieved.

In maximum heating mode, when the infrared lamps 4 and 10 are on full power, the switches 1,2,6,7 and 11 are in the closed position.

The reduced heating mode is obtained at the closed switches 1 and 11 with the switches 2,6 and 7 in the off position. The infrared lamps 4 and 10 are then connected to the mains line voltage between terminals a and b.

Discrete heating modes are obtained by closing the switches 1,2,6,7 at the unlocked switch 11 when the infrared lamp 4 is illuminated, and by switching the switches 2,6,7,11 at the unlocked switch 1 when the infrared lamp only 10 is lit.

In order to obtain a selective ultraviolet radiation mode, the light source receives power from a zero point 0 of an analogue device (not shown) at closed switch 6, but at unlocked switches 1,2,7 and 11, whereby the light source circuit is switched off at the power supply unit.

Similarly, from an apparatus described elsewhere to an apparatus located elsewhere, the power supply for ultraviolet radiation may be supplied to the closed switches 1,11 and 7 and to the unlocked switches 2 and 6.

By eliminating the need to use ballast ballasts and a low-voltage transformer, the unit's total capital investment is reduced by 20%, while its operating costs reduce its operating costs by 15%.
