Description

Dual-purpose high-voltage three-phase unilateral electricity inspection device

This creation is about a dual-purpose high-voltage three-phase single-sided electricity inspection device, especially a novel structure technology that can visually detect and monitor whether the high-voltage three-phase unilateral electrification is normal at any time.

In addition to providing the high-voltage electricity value that we generally use in our daily life, the high-voltage electricity output from the power plant also has three-phase high-voltage electricity. It is mostly used in large power-consuming equipment and various power-using factories. It can be said that three-phase high-voltage In the case of AC power, a power outage is often caused by a heavy shutdown of the production line, and it is even more undesirable for power outages. On-site maintenance personnel often cannot visually determine which phase of the three phases are out of power, resulting in the risk of electric shock due to further testing. It may be necessary to repair all the power outages, and it is more urgent for the naked eye to immediately determine the phase failure and the need to immediately restore the power. However, the traditional three-phase high-voltage power facilities draw power from each side of the three-phase high-voltage overload disconnector. After that, if the relevant phase ends are energized or abnormally powered off, it is often impossible to visually determine which phase of the circuit is powered off, and one by one must be inspected, resulting in maintenance risks. If there is no maintenance technician on site, the three-phase high voltage cannot be immediately known The phase loss of electricity has occurred, and when all the power failures are known, it will often cause more damage. These highlights that facilities should be developed and installed to detect the power outage with the naked eye of the high-voltage three-phase unilateral standing. The location and power-off remote notification mechanism is important, and can solve the current dilemma where the power-off circuit cannot be judged and the remote end cannot be known.

In view of the fact that conventional three-phase high-voltage power facilities do not have high-voltage three-phase unilateral standing automatic inspection To test the lack of electrification, the creator is actively conceiving a solution. After many trials, the original creation has finally come into being.

Therefore, this high-voltage three-phase unilateral electrical inspection device is a three-phase electrified inspection unit and an external signal transmission unit installed in the box, in which the electrical inspection unit is output by three sets of AC to DC circuits After each end is connected to the step-down driving indicator circuit, a live indicator is connected in parallel, and then a varistor is connected. These step-down driving indicator circuits are sent to the inspection signal external transmission unit by another communication terminal. The detection signal external transmission unit is mainly composed of an optical coupler, an adjustment circuit, a relay, a diode, an OR gate, an NO gate, an external transmission power indicator lamp, a transistor switch, and a monostable multivibrator circuit, and is composed of an adjustment circuit The external input power supply is introduced into the input terminal, and the external power supply is stepped down and rectified and then sent to the relay coil, and then to the import terminal of the transistor switch. The export terminal of the transistor switch is connected to the ground through the monostable multivibrator circuit, and the transistor switch is activated. Connect the gate in series to the output of the output side of the optocoupler, and to the trigger end of the monostable multivibrator circuit. The input of the output side of the optocoupler is connected to the input end of the relay coil, and the other end is grounded, or the gate output is connected On the input side of the optocoupler, a diode is connected in parallel to the relay coil, thereby connecting the input end of the AC-to-DC circuit to the appropriate position of each phase end of the three-phase high-voltage overload disconnector, you can check from the live indicator Know whether it is normally energized. When there is no power supply in all three phases, the detection signal can be transmitted through the auxiliary contact of the relay to the alarm device or remote monitoring equipment and other warning devices, so that all phases can be known from a distance Immediately go to repair after power failure to restore the power as soon as possible, this is the purpose of this creation.

In addition, this high-voltage three-phase single-sided electrical inspection device is created. At the input terminals of the three sets of AC to DC circuits of the live detection unit, a conductive connecting plate can be specially provided to connect the three sets of AC to DC circuit input terminals in parallel into a single line It is extended, and the box body is especially composed of the box end cover with a box face cover and an additional box face cover shutter. The box face cover corresponds to each light-emitting end of the live indicator and the external power supply finger The light emitting end of the indicator light is provided with dew holes respectively, and the box surface cover shutter is only provided with a dew hole for the light emitting end of the charged indicator and the light emitting end of the external power supply indicator connected to the set of AC to DC circuits which are collectively bundled in parallel. The cover structure of the cover and the surface of the box is covered with a connection structure of a conductive connection plate, so that this high-voltage three-phase single-sided electrical inspection device can be connected to a line on one side of a phase separately, using three boxes for tapping Three-phase single-sided, you can detect all three-phase single-sided, from the live indicator to see whether the corresponding side of the connected phase line is normally charged, so as long as there is any phase unilateral power outage, At this time, the detected power-off signal can also be transmitted through the box connected to it separately, so that the relay in it can be activated, and the auxiliary contact of the relay can be transmitted to the alarm device such as the alarm device and remote monitoring equipment, etc. In order to determine which phase is off and which side is out of power according to the information from afar, immediately report for repair and immediately restore the power to reduce the loss. This is another purpose of this creation.
