Problems solved by technology
With the popularization of unattended substations, the intelligent requirements for inspection equipment are getting higher and higher. The original plug-in charging is difficult to meet the requirements of intelligent inspection. How to realize the power inspection equipment in an unattended state Energy management has become a major research topic in the industry
[0003] With the maturity of wireless charging transmission technology, it has become possible to use wireless charging for power inspection equipment. However, due to the mobility of the receiving end of the secondary side, it will take a long time to sample a single transmitting coil and a single receiving coil. Staying in a fixed charging area makes it difficult to meet dynamic charging requirements

Embodiment Construction
[0027] The specific implementation manner and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0028] like figure 1 , figure 2 As shown, this embodiment provides a cascaded wireless charging system for power inspection robots. The inspection path of the original edge power inspection robot is laid with 5 levels of transmitting coils. Of course, the number can be set to be more, and each level of transmitting coils is rectangular. Each level of the transmitting coil is in the shape of a guide rail. Each level of transmitting coil is connected with its own compensation capacitor to form a first-level resonant circuit. The adjacent two-level transmitting coils are coupled by a U-shaped magnetic core. Relative to each level of resonant circuit It is equipped with a sensor for detecting whether the load enters and a power switch for controlling whether the resonant circuit is on or off. The first...

The invention discloses a cascaded wireless charging system of an electric power inspection robot and a control method. The system is characterized in that a primary side is provided with multiple stages of transmitting coils, each stage of transmitting coil is connected with a respective compensation capacitor to form a first-stage resonance circuit; every two adjacent stages of transmitting coils are coupled through a U-shaped magnetic core, a sensor used for detecting whether a load enters and a power switch used for controlling the on-off of the resonance circuit are arranged relative to each stage of resonance circuit, a first-stage transmitting coil takes electricity from a high-frequency inverter on the primary side, the other transmitting coils take electricity from a last-stage transmitting coil through the U-shaped magnetic core, and when the load enters an nth-stage wireless charging transmitting guide rail, the system controls the power switches corresponding to the first-stage transmitting coil to an nth transmitting coil be in a closed state. The invention has the effect that the dynamic wireless charging of the electric power inspection robot can be met.
Description
technical field [0001] The invention relates to wireless charging technology, in particular to a cascaded wireless charging system and control method for a power inspection robot. Background technique [0002] In each substation, in order to realize the daily inspection of various power equipment, a power inspection robot is usually equipped. With the popularization of unattended substations, the intelligent requirements for inspection equipment are getting higher and higher. The original plug-in charging is difficult to meet the requirements of intelligent inspection. How to realize the power inspection equipment in an unattended state Energy management has become a major research topic in the industry. [0003] With the maturity of wireless charging transmission technology, it has become possible to use wireless charging for power inspection equipment. However, due to the mobility of the receiving end of the secondary side, it will take a long time to sample a single tran...
