Embodiment 1
[0035] A combined thin film capacitor for electric vehicle charging pile comprising an outer casing 1 of the upper end opening, an outer cover 2 is attached to the upper opening of the outer casing 1, and there are two vertical interposers on the outer cover 2. The total terminal 3, the side wall of the outer casing 1 is a multi-faceted structure, and the outer casing 1 includes a plurality of hous portions 101 that are distributed in an annular array and a plurality of bevers portions 102 connected to the plurality of hous portions 101, and the outer casing 1 The middle cavity is provided with a hollow boss 4, and there is a plurality of branch capacitance unit 9 and the housing portion 101;
[0036] In this embodiment, if Figure 2-3 Design, the upper end edge of the hollow boss 4 is mounted having a second conveyor line 7, and the second paper-on-board line 7 is provided with a first paper-back line 6, and the first paper-back line 6 and the first The branch terminal block 8 di...
Embodiment 2
[0045] The difference from the first embodiment is that the interior of the hollow boss 4 is mounted with a total capacitance unit constructed within the branch capacitance unit 9, and two divided terminals II of the total capacitance unit are respectively wiring. The terminal 3 is connected, each branch capacitance unit 9 is combined with the total capacitance unit, and the total capacitance unit is a relay, more efficient integration of a plurality of branch capacitance unit 9, forming a whole, and is used for charge and discharge of electric vehicle charging piles. .
[0046] Other non-description structural reference Example 1.
Embodiment 3
[0048] The difference from the first embodiment is that figure 2 with 3 Design, a plurality of heat dissipating holes are provided on the beveled side portion 102, and the inner wall of the beveled side portion 102 is thermally mounted, the heat dissipation fan 13 mates with the heat dissipation hole, which can effectively ensure the overall heat dissipation effect of the combined thin film capacitor, Flame retardant, cooling.
