Anonymous users2024-02-05Transmission line CT energy extraction device is a new type of power supply device that uses the principle of electromagnetic induction to obtain electric energy and achieve stable voltage output. At present, there are some domestic manufacturers that can provide this kind of power supply, but many of them have problems such as unstable output voltage, great influence by current changes in transmission lines, and high heating. The TLPS series transmission line energy extraction device has stable and reliable long-term operation, mature technology, strong adaptability to transmission line current changes, short circuit and impulse current self-protection, and can provide reliable power supply for all kinds of transmission line monitoring and monitoring equipment.

Anonymous users2024-02-03The high-voltage side measurement equipment of the power system, such as the transmission line temperature measurement equipment, the high-voltage circuit breaker bus temperature measurement equipment, etc., directly measures the high-voltage side information, and then transmits the collected information to the low-voltage end through optical fiber or wireless network, which greatly simplifies the insulation requirements, and improves the accuracy of the collected signal, but the high-voltage side measurement equipment cannot directly supply power to it through the low-voltage side wire, so the power supply problem of the high-voltage side measurement equipment is one of the keys to the reliable operation of the high-voltage side measurement equipment. In recent years, a current transformer is installed on the high-voltage bus, and the induced voltage of the secondary side of the transformer is obtained by obtaining the bus current and then converting it into the above-mentioned working power supply, that is, the method of CT power taking, which effectively solves the problem of the working power supply of the high-voltage side measuring equipment, but the bus current changes in a large range with the change of line load, so that the induced voltage of the secondary side also changes in a large range, which brings great difficulty to the design of CT power supply. In the range of large variation of primary current, the output of the power taking coil is relatively stable, and a wide current range CT power taking device is provided, which can realize that the CT power taking device works normally and the output is stable in the large range of transmission line current change, and the serious heating phenomenon of the current transformer is avoided, and the circuit is simple and the cost is low.

There are many advantages of smart pianos, first of all, the cost is relatively low, for people who have piano learning needs, smart pianos can save an expense; For amateur piano lovers, smart pianos can freely arrange, change rhythm and timbre, and are more interesting. The disadvantage of smart piano is that the timbre strength of the piano is different from that of the real piano, which will have a certain impact on piano learners, and only a few high-cost electric pianos can be compared with the real piano.
