Embodiment Construction

[0027] figure 1 Shows the modular mechanical parts of the present invention. The circuit breaker module 14 includes a vacuum interrupter / linear actuator assembly. Although Figure 3(a) shows that only the vacuum interrupter part of the component is sealed in a solid insulated housing 24 (such as epoxy, silicon, polyurethane, etc.), it should be understood that the entire unit can also be sealed In an insulated housing, however, the actuator does not need to be insulated in this way because it is a lower voltage component. The vacuum interrupter portion 26 of the circuit breaker module 14 is a conventional circuit breaker vacuum interrupter design, which is 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. The movable contact 30 is actuated by a push rod / movable contact bar assembly 32, which is slidable The container 34 is ground and sealedly inserted and the movable contact 30 is...

Abstract

A compact switchgear system (10) employing a number of modular components (12, 14, 16 and 18) that plug into their mating interface and are maintained in electrical isolation employing solid insulation (24, 70 and 82) in a manner that substantially shields the electrical conducting portions of the assembly from contact with lower voltage portions of the system. The assembly is primarily made up of five modules. A multi-phase load connector (16) having integral current monitoring transformers (80) for each of the respective phases; a voltage monitoring transformer (18) which plugs into the load connector (16); an in-line actuator and vacuum interrupter module (14), provided for each phase, which plugs into the load connector (16); a three position vacuum switch (12) connected between the vacuum interrupter module (14) and the line or ground; and an electronic control module (84) which receives inputs from the current and voltage monitors (80, 18), circuit relays, vacuum interrupter / in-line actuator module (14), and temperature sensors (94), and provides programmed, controlling outputs (96) to the in-line actuators of the respective vacuum interrupter modules (14).

Description

[0001] Cross reference to related applications [0002] This patent application involves the corresponding serial number __ (agent file 98-PDC-065), serial number __ (agent file 97-PDC-524) and serial number __ (agent file 97-PDC-611) US patent applications; they are all filed at the same time as this application. Technical field [0003] Generally speaking, the present invention relates to switchgears and other switchgears that use sealed interrupters with insulation higher than air resistivity, and more specifically, to compact switchgears that utilize modular components to Reduce the overall size of the system. Background technique [0004] Circuit breakers provide protection to the electrical system from electrical fault conditions such as current overload, short circuit, and abnormal voltage levels. Generally, a circuit breaker includes an operating mechanism powered by a spring, which responds to abnormal conditions by opening electrical contacts to interrupt the current pas...
