Abstract
Power distribution busses and methods are disclosed that provide flexible protection and alarming capabilities. Various embodiments provide interchangeability of fuses and circuit breakers within the same power distribution bus configuration. These various embodiments also provide discrete alarming for fused lines, discrete alarming for lines with circuit breakers, combined alarming for lines having mixed forms of protection, and/or selectable alarming such as combined versus discrete in relation to employing all fused lines, employing all circuit breaker protected lines, or employing mixed line protection.
Claims21
A method of providing circuit protection for a power distribution bus, comprising the steps of:
- inserting a first fuse with an alarm connector in a first socket, the first socket having three alarm connections and two power connections, such that the alarm connector of the first fuse connects to the second alarm connector of the first socket;
- inserting a second fuse with an alarm connector in a second socket, the second socket having three alarm connections and two power connections, such that the alarm connector of the second fuse connects to the second alarm connection of the second socket;
- and
- inhibiting a response from an alarm circuit electrically linked to the first socket and the second socket until the first fuse or the second fuse is blown.
A power distribution bus alarm circuit, comprising:
- a first socket and a second socket, each having three alarm connections and two power connections;
- alarm circuit connected to first and second alarm connections of the first and second sockets, the alarm circuit being responsive to a voltage being applied from the second of the three connections of the first or second socket and being responsive to a voltage being applied across first and third connections of the first or second sockets;
- and
- a voltage source electrically connected to a third alarm connection of the first and second sockets.
A power distribution bus alarm circuit, comprising:
- a first location and a second location, each having at least three alarm connections and two power connections;
- and
- an alarm circuit connected to first and second alarm connections of the first and second locations, the alarm circuit being responsive to a voltage being applied from the second of the three connections of the first or second socket and being responsive to a voltage being applied across first and third connections of the first or second locations.
