- Fault current, or momentary current surges, in the system can occur under various conditions, including lightning, an animal or tree contacting the power lines, or adjacent power lines contacting each other.
- windy conditions often cause power lines strung between poles to swing, thereby momentarily touching each other or a grounded conductor.

Description
- This application is a continuation of U.S. application Ser. No. 15/584,917 filed May 2, 2017 which is based on U.S. provisional application Ser. No. 62/330,355, filed May 2, 2016, the disclosure of which is incorporated herein by reference in its entirety and to which priority is claimed.
- Various exemplary embodiments relate to a battery assembly for a utility line circuit interrupter such as a recloser.
- Conventional circuit interrupting devices, such as circuit breakers, and reclosers, provide protection for power distribution systems and the various apparatus on those power distribution systems by isolating a faulted section from the upstream power source in the system. Fault current, or momentary current surges, in the system can occur under various conditions, including lightning, an animal or tree contacting the power lines, or adjacent power lines contacting each other. For example, windy conditions often cause power lines strung between poles to swing, thereby momentarily touching each other or a grounded conductor. These types of transitory events cause momentary power line short circuits that in turn cause fuses to burn out or circuit breaker to trip.
- Most of the faults occurring on a line are transient faults, as opposed to permanent faults, and do not require permanent protection. Therefore, reclosers are a common solution for clearing these types of transient faults without causing a permanent power outage. Reclosers are typically mounted to support structures in electrical power distribution systems to provide continuous electrical service up to a programmed current threshold. Reclosers detect faults, i.e., overcurrent events past the programmed threshold, and interrupt the load current when the overcurrent event persists for a predetermined amount of time which is determined by the overcurrent value. If the recloser operates and temporarily interrupts the load current, it will automatically restore service after the transient fault condition is gone. If a fault is permanent, the recloser locks out, i.e., permanently opens the circuit, after a preset number of operations, thereby isolating the faulted section of the system.
- According to an exemplary embodiment, a circuit interrupting device for use within a power distribution system includes a housing containing a circuit interrupting mechanism. A battery tube is positioned in the housing. A battery assembly is configured to be inserted into the battery tube. The battery assembly includes a battery assembly body having a first end and a second end. A battery is positioned within the battery assembly body. A positive contact is electrically connected to the battery and is exposed from the second end of the battery assembly body. A negative contact is electrically connected to at least one of the one or more batteries and exposed from the second end of the battery assembly body.
- According to another exemplary embodiment, a circuit interrupting device for use within a power distribution system includes a housing containing a circuit interrupting mechanism. A battery tube is positioned in the housing. The battery tube has a first mating feature, a first positive contact, and a first negative contact. A battery assembly is configured to be inserted into the battery tube. The battery assembly includes a second mating feature configured to mate with the first mating feature, a second positive contact, and a second negative contact. The first and second mating features ensure a proper alignment of the battery assembly in the battery tube to electrically connect the first and second positive contact and electrically connect the first and second negative contacts.
- According to another exemplary embodiment, a circuit interrupting device for use within a power distribution system includes a housing containing a circuit interrupting mechanism. A battery tube is positioned in the housing. A battery assembly is configured to be inserted into the battery tube.
