Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The invention provides a thyristor high-voltage suspension trigger, which is powered by a battery, and a control signal is transmitted from a low-voltage end to a high-voltage end through an optical fiber. The suspension trigger does not need to isolate the trigger pulse generating circuit and the heating voltage generating circuit respectively, and only needs to realize the overall isolation of the trigger device to the ground, thereby simplifying the structure of the device and improving the operational reliability of the trigger device. The operating temperature of the hydrogen thyristors has a large impact on the switching performance and life span, however, in order to simplify the structure of the thyristors themselves, conventional thyristors do not provide a temperature measuring interface. The invention introduces an infrared thermometer which is attached to the surface of the thyratron tube, digitizes the temperature information and outputs the temperature information through the optical fiber, thereby realizing the feedback control of the working temperature of the thyratron tube. On the charging scheme of the trigger battery, the invention provides a wireless charging mode, which ensures that a low-voltage power supply end is completely and electrically isolated from the trigger, and realizes reliable isolation between high-voltage ends and low-voltage ends.
In the prior art, the generation of a trigger signal of a trigger is always finished at a low-voltage end, and the trigger signal is amplified and then connected to a hydrogen thyratron at a high-voltage end, so that the reliable electrical isolation between the high-voltage end and the low-voltage end is the basic function of the trigger. The trigger isolation is generally realized by adopting an isolation transformer, and at least two isolation transformers are needed for isolating the heating loop and the trigger pulse loop respectively, so that the size and the weight of the trigger are large, and the system integration level is not improved favorably.
According to the high-voltage suspension trigger provided by the invention, the whole trigger is suspended at the high-voltage end with the same potential as the thyristor, so that high-voltage isolation is not required between the trigger and the thyristor, and only the integral isolation between the trigger and the low-voltage end is required, and the high-voltage suspension trigger is easily realized through the external packaging of the trigger. The trigger saves a heavy high-voltage isolation transformer, effectively reduces the volume and the weight, simultaneously reduces the number of connecting circuits, simplifies the system structure and improves the system reliability. The power supply of the trigger is realized by adopting a battery, the trigger signal is transmitted by adopting optical fibers, the complete isolation of the trigger and the low-voltage control end is realized, and the problem that the low-voltage control end is damaged due to the fact that an isolation transformer in the traditional trigger is possibly broken down can be effectively avoided.
Fig. 1 shows a circuit configuration of the flip-flop. The circuit mainly comprises a lithium battery, a heating voltage generating circuit and a trigger pulse generating circuit, the whole trigger works in a suspension high-voltage state, and control signals are transmitted through optical fibers. The lithium battery is a power supply of the whole trigger, the heating circuit comprises a half-bridge circuit and an LC filter circuit, the output heating voltage of the heating circuit is determined by the duty ratio of a PWM (pulse-width modulation) driving signal of the half-bridge circuit, and the PWM driving signal is controlled by a temperature feedback system. And the generation process of the trigger pulse is described as follows: firstly, an adjustable DCDC boosting module charges a high-voltage trigger capacitor to a proper voltage value, then the IGBT is controlled to be conducted through a trigger signal, the capacitor discharges to a pulse transformer, and a required high-voltage trigger pulse is generated on a secondary side of the transformer.
The invention provides an infrared temperature measurement scheme, wherein an infrared thermometer is attached to the surface of a thyristor, signals are converted into light pulses after being digitally modulated, and temperature signals are easily fed back to a low-voltage control end through optical fibers in actual use so as to realize temperature feedback control.
The temperature feedback control schematic is shown in fig. 2. The real-time temperature of the thyristor is measured by an infrared thermometer attached to the surface of the thyristor and fed back to a control system, the real-time temperature of the thyristor is compared with the optimal trigger temperature of the given thyristor and then processed to generate a PWM heating signal with a proper duty ratio, and the heating signal is transmitted to a trigger through an optical fiber, so that corresponding heating voltage is generated to heat the thyristor.
The high-voltage suspension trigger is powered by a battery, the charging of the battery becomes an interface between high voltage and low voltage, and how to realize high-efficiency charging on the premise of high-voltage isolation is an important problem. If the charging is carried out in a wired mode and the charging interface is disconnected during the working period of the thyristor, effective isolation can be realized, but online charging cannot be realized, and meanwhile, if the charging interface is not disconnected for some reason, the charging loop is easy to damage at high voltage.
The lithium battery is used as a trigger power supply, the energy of the lithium battery is provided by commercial power through a wireless charging module, the wireless charging module is composed of a transmitting plate, a transmitting coil, a receiving coil and a receiving plate, the four lithium battery is placed in a laminated structure, four corners of the four lithium battery are supported by threaded columns, and high voltage between the transmitting coil and the receiving coil is isolated by a large epoxy plate.
In order to realize reliable isolation, the invention provides a wireless charging mode, wherein no electrical contact exists between a wireless transmitting coil and a receiving coil, so that the electrical isolation of a high-voltage side and a low-voltage side can be effectively realized, and the possibility of damaging a low-voltage end due to faults is avoided; meanwhile, the online charging of the battery can be realized in the mode, the convenient charging when the electric quantity is insufficient can be realized, and the cable is not required to be detached or connected.
The wireless charging principle is shown in fig. 3. Commercial power generates alternating current in the transmitting coil after being rectified and frequency-converted by the transmitting plate, energy is transferred to the receiving coil from the transmitting coil by utilizing the principle of electromagnetic induction, and then the lithium battery is charged after being rectified by the receiving plate.
The trigger system isolation structure is shown in fig. 4. The whole trigger 3 is placed in a metal shielding box 2, and because the trigger works in a suspension high-voltage state, the trigger and the metal shielding box are fixed in an insulating box 1 made of acrylic plate materials for high-voltage isolation from the outside, input control signals on the trigger are all led in through optical fiber lines, and the output end of the trigger is led out to a thyristor through a high-voltage cable.
