Embodiment Construction

[0043] figure 1 A modular mechanical part 10 of the present invention is shown. The circuit breaker module 14 contains a vacuum interrupter / linear actuator assembly. Although FIG. 3(A) shows only the vacuum interrupter portion of the assembly sealed within a solid insulated housing 24 (e.g., epoxy, silicon, polyurethane, etc.), it should be understood that the entire unit could also be sealed. In an insulated housing, however the actuator does not have to be so insulated since it is a lower voltage component. The vacuum interrupter portion 26 of the circuit breaker module 14 is of a conventional circuit breaker vacuum interrupter design, more fully shown in FIG. 3 . The vacuum interrupter 26 is housed in a sealed container 34 and includes a stationary contact 28 and a movable contact 30 which is actuated by a push rod / movable contact bar assembly 32 which is slidable The receptacle 34 is inserted and sealed and is operable to move the movable contact 30 into engagement or d...

Abstract

A compact open-box equipment system (10) utilizing several modular components (12, 14, 16 and 18) which plug into their mating interfaces and maintain electrical isolation using solid insulation (24, 70 and 82), allowing It essentially blocks the assembly from contact with the lower voltage parts of the system. The combination mainly consists of 5 modules: the multiphase load connector (16), with integrated current monitoring transformer (80) for each of the phases; the voltage monitoring transformer, which plugs into the load connector (16 ); inline actuator and vacuum interrupter module (14), which is provided for each phase and plugs into the load connector (16); three-position vacuum switch (12), connected to the vacuum interrupter module ( 14) and line or ground; and the electronic control module (84), which consists of current and voltage monitors (80, 18), circuit relays, vacuum interrupter / embedded actuator modules (14), and temperature sensors (94) receives input and provides programmed control output (96) to the embedded actuator of each vacuum interrupter module (14).

Description

technical field [0001] The present invention relates generally to switchgear and other switchgear that utilize sealed interrupters employing insulation with a higher resistivity than air, and more particularly to compact switchgear that utilizes modular components to Reduce the overall size of the system. Background technique [0002] Circuit breakers provide protection for electrical systems from electrical fault conditions such as current overloads, short circuits, and abnormal voltage levels. Generally, circuit breakers include a spring-energized operating mechanism which, in response to abnormal conditions, opens electrical contacts to interrupt the flow of electrical current through conductors on an electrical system. In particular, a vacuum circuit interrupter device is known which comprises separable main contacts placed in an insulating housing. Typically, one of the contacts is fixed relative to the housing and an external electrical conductor that interconnects t...
