US 2019/0058324 A1 · CIRCUIT FORMING METHOD AND HYDROGEN STATION

Abstract

A circuit forming method is a method for forming a circuit in which an electrical component and an intrinsically safe explosion-proof related device are electrically connected, in a facility where the electrical component is disposed in a hazardous area and the intrinsically safe explosion-proof related device for limiting a current is disposed in a non-hazardous area. In this method, a first connector to be electrically connected to the electrical component and a second connector to be electrically connected to the intrinsically safe explosion-proof related device are connected in the hazardous area, thereby forming the circuit in which the current is limited by the intrinsically safe explosion-proof related device and grounding a shielding pin provided in the first connector or the second connector only at one position in the non-hazardous area.

A circuit forming method for forming a circuit in which an electrical component and an intrinsically safe explosion-proof related device are electrically connected, in a facility where the electrical component is disposed in a hazardous area and the intrinsically safe explosion-proof related device for limiting a current is disposed in a non-hazardous area, wherein

a first connector to be electrically connected to the electrical component and a second connector to be electrically connected to the intrinsically safe explosion-proof related device are connected in the hazardous area, thereby forming the circuit in which the current is limited by the intrinsically safe explosion-proof related device and grounding a shielding pin provided in the first connector or the second connector only at one position in the non-hazardous area.

A hydrogen station provided with a hazardous area and a non-hazardous area, comprising:

an electrical component to be disposed in the hazardous area;
an intrinsically safe explosion-proof related device to be disposed in the non-hazardous area and configured to limit a current;
a first connector electrically connected to the electrical component;
and
a second connector to be electrically connected to the intrinsically safe explosion-proof related device and connected to the first connector in the hazardous area;
wherein
a circuit in which the electrical component and the intrinsically safe explosion-proof related device are electrically connected and a current is limited by the intrinsically safe explosion-proof related device is formed by connecting the first connector and the second connector and
a shielding pin provided in the first connector or the second connector is grounded only at one position in the non-hazardous area.
