circuit breaker

Voorbeeldzinnen

1. Type of circuit breaker: …
2. FUSE AND/OR CIRCUIT BREAKER
3. indicator of state of main automatic line voltage circuit breaker;
4. Before running through system separation sections the traction unit’s main circuit breaker shall be opened.
5. Circuit breaker tripping in substations and on trains has to be coordinated.
6. Every electrical circuit feeding an item of equipment other than the starter, the ignition circuit (positive ignition), the glow-plugs, the engine-stopping device, the charging circuit and the battery earth connection shall include a fuse or a circuit breaker.
7. They may, however, be protected by a common fuse or a common circuit-breaker, provided that its rated capacity does not exceed 16A.
8. Electrical supply line: The line between the current collector or current source and the main circuit breaker or the main fuse(s) on the vehicle.
9. provision shall be made in the energy subsystem to avoid bridging of both adjacent power supply systems should the opening of the on-board circuit breaker(s) fail,
10. On leaving the separation section, the devices shall cause the main circuit breaker to be closed and power consumption to be resumed.
11. Electrical resistance between all metal parts of the rolling stock and the rail shall be low enough to ensure that rising short circuit current will cause disconnection of circuit line breaker (e. g. when the catenary falls on a wagon).
12. The relevant product market for low-voltage switchgear (‘LV switchgear’) can be segmented into three submarkets according to the built-in circuit breaker which can be an ACB, MCB or MCCB.
13. The return current paths and the protective bonding (earthing cable) of the vehicle shall be able to withstand the maximum short circuit current until disconnection by infrastructure circuit line breaker (substation) without damaging the current paths itself or parts of the vehicle.
14. As a minimum, these devices shall enable power consumption (both traction and auxiliaries, and for the no load current of the transformer) to be automatically brought to zero and the main circuit breaker opened before the traction unit enters a separation section, without the intervention of the driver.
15. However, it appears from the structure of the GIS, HV-turnkey and circuit-breaker markets (three close competitors, inhomogeneous products, large customers) and the observed bidding pattern (all competitors participate successfully in tenders throughout Europe) that any effective coordination mechanism in the GIS market would have to be highly elaborate and would be difficult to implement.
