Embodiment Construction

[0043] With reference to these figures, a medium voltage circuit breaker according to the invention is denoted by reference number 1 and, in its broader definition, comprises a pole assembly 2 having, for each phase, accommodating a first fixed Interruption chamber for contact and second moving contact. (The fixed and moving contacts are not shown in the accompanying drawings). Usually said circuit breaker is a three-phase circuit breaker and therefore comprises three interruption chambers 6, 7 and 8, which accommodate the corresponding set of fixed / movable contacts, wherein said movable contacts can be between the open position and the closed position Disconnect / connect back and forth. The fixed and moving contacts may be of a conventionally known type and will therefore not be described in more detail.

[0044] The circuit breaker according to the invention also comprises an actuator 3 to actuate the opening and closing operations of said circuit breaker. Such as Figure...

Abstract

A Medium Voltage circuit breaker which comprises a pole assembly having, for each phase, an interruption chamber housing a first fixed contact and a second movable contact reciprocally couplable / uncouplable between an open and close position; the Medium Voltage circuit breaker further comprises an actuator to actuate the opening and closing operation of said circuit breaker and an insulating base frame supporting said pole assembly and said actuator.

Description

technical field [0001] The present invention relates to a medium voltage circuit breaker with improved features, in particular to a medium voltage circuit breaker with simplified construction. The term "medium voltage" for the purposes of the present invention refers to applications in the range of 1-52 kV. Background technique [0002] Medium voltage circuit breakers are well known in the art. They usually consist of a pole assembly with fixed and moving contacts for each phase. The moving contact generally moves between a first position in which the moving contact is connected to the fixed contact and a second position in which the moving contact Opening and closing operations of the circuit breaker are achieved by disconnecting from the fixed contacts. [0003] The pole assembly is usually mounted on a base frame, which is generally made of a number of individual elements of metallic material assembled by screws and / or welding. The actuators for actuating the opening ...
