してしまい極めて不都合である。 Among the terminal connections for power cables, the terminal connections that are directly connected to power equipment such as transformers and circuit breakers generally include the cable body, reinforcing insulator, insulator filled with insulating fluid, etc. inside the insulating pipe. Typically, such terminal connections and power equipment are connected to each other within a metal case filled with an insulating fluid. In such a conventional terminal connection section, a radiator is installed at the top of the insulator tube in order to effectively radiate heat generated from the insulator tube section. However, when such a radiator is installed, unless sufficient heat is radiated from the metal case to the outside, heat will accumulate in the insulating fluid inside the metal case, causing a temperature rise and reducing power transmission capacity. This is extremely inconvenient.

されている。 FIG. 1 is a partial cross-sectional view of an embodiment of the present invention, in which a heat radiator 2 is provided at the top of an insulator tube 1, and a direct connection type cable termination is directly connected to power equipment (transformer, gas insulated switch, etc.). A connection is formed. This connection part is housed in a metal case 3 filled with an insulating fluid 5 such as insulating oil (in the case of a transformer) or insulating gas (such as SF 6 , however, in the case of an SF 6 gas-insulated switchgear). A coolant conduction path 6 for introducing a coolant 7 through the bottom plate 4 is installed in this metal case.
導入されるべき冷媒としては通常の冷却用媒体

可能となる。 In this embodiment, the heat generated at the end of the cable is radiated into the insulating fluid 5 through the radiator 2, but the insulating fluid 5 is constantly cooled by the action of the refrigerant 7 circulating through the refrigerant conduction path 6. , heat is not accumulated in this part and heat is dissipated extremely effectively. Therefore, compared to a conventional structure without a refrigerant conduction path, the heat dissipation characteristics are extremely good, the allowable current can be increased, and the power transmission capacity can be increased.
