The utility model discloses a quick detachable sealing structure, including sealing bolt, sealing ring and sealing groove, sealing bolt has head and screw rod part, and screw rod part is suitable for screw hole, and sealing ring is sleeved on the screw rod part of sealing bolt. The quick detachable sealing structure is through the sealing bolt is spun into screw hole, and the head lower end surface will extrude sealing ring, makes it fill the gap between lower end surface and sealing groove and microcosmic uneven place fully, forms the dead angle -free sealed interface, and sealing ring is sleeved on the outer periphery of screw rod part, can form the auxiliary seal with screw hole entrance hole wall simultaneously, double -guarantee blocks the helium gas leakage path, avoids the sealing failure problem caused by traditional sealant partial check crack, quick plug connector sealing ring misplacement, utilizes the static seal of sealing ring under the pressure deformation of end face, and the sealing effect is excellent, only needs to tighten or loosen sealing bolt and can realize the sealing or disassembly, and the disassembly process does not need the violent operation, and the tool body thread or sealing element itself will not be damaged.

The application discloses a BWPT system power control method suitable for a variable receiving end of an electric vehicle. The system is composed of a network side and a vehicle side DC bus, a filter capacitor, a bidirectional full-bridge converter, a resonance compensation network, a magnetic coupling mechanism and a sampling and digital control module. The receiving end receiving coil structure is variable, and LCC or S compensation can be adopted. In the forward charging and reverse power feedback mode, the control module is based on the DC side voltage sampling and the power analysis model, and the rated output power is the primary target, and the system driving frequency and the external phase angle are adjusted. The method can realize stable and practical power control under the condition of "fixed primary side and variable secondary side".

The invention relates to the technical field of skid-mounted transformer substations, in particular to a skid-mounted transformer substation based on an intelligent power distribution network, and solves the problems that when an existing skid-mounted transformer substation is applied, a used insulating medium cannot continuously keep pure quality, and positive voltage insulation treatment is inconvenient to carry out on the transformer substation through the insulating medium. Comprising a box type protection mechanism, an insulation regulation and control mechanism is installed on the inner side of one end of the box type protection mechanism, the insulation regulation and control mechanism comprises an insulation gas conveying module, a backflow heat dissipation module is installed on the inner side of the insulation gas conveying module, and a circulation purification module is installed on one side of the backflow heat dissipation module. The backflow heat dissipation module comprises a heat dissipation box, and a condenser is fixedly installed at the bottom end of the heat dissipation box. Through the backflow heat dissipation module and the circulating purification module, circulating conveying and processing of insulating gas are facilitated, and insulating operation of a transformer substation in the protection box and the quality of the insulating gas are kept.
