Example Embodiment

[0020] Example 2: Such as figure 2 As shown, the difference from Embodiment 1 is that, as shown at S, the mounting cavity is set in a stepped shape, and the outer circumference of the current transformer 3 is set in a stepped shape to fit it accordingly, which has a better gear. Stop limit effect.

[0021] In other embodiments: the current transformer installed in the solid-sealed pole can be an electronic type or an electromagnetic type.

Abstract

The invention relates to a solid-sealed polar pole of an integrated current transformer. The solid-sealed polar pole comprises a vacuum arc-extinguishing chamber and a shell, the shell is provided with an outgoing line wiring end, the inner end of the outgoing line wiring end is connected with a moving end conducting rod, and the solid-sealed polar pole further comprises a current transformer which sleeves the moving end conducting rod and located between the bottom wall of the vacuum arc-extinguishing chamber and the outgoing line wiring end. When the vacuum arc-extinguishing chamber is conducted, the bus is conducted and forms the primary side of the current transformer, and the secondary side of the current transformer can sense the current change, thereby achieving the detection of thebus current. The current transformer is arranged on the moving end conducting rod, the space extending up and down of the moving end conducting rod can be utilized and is subjected to solid-sealing in the shell of the solid-sealed polar pole to form a highly integrated whole without extra addition of a large space, so that the volume occupation of the current transformer is greatly reduced, and structural members necessary for installing and fixing the current transformer are saved, thereby further reducing the volume occupation of the current transformer in the switch cabinet.

Description

Technical field [0001] The invention relates to a solid-sealed pole of an integrated current transformer. Background technique [0002] With the continuous development of the electric power industry, people have put forward higher and higher requirements for the manufacture of switchgear. Under the premise of ensuring quality, miniaturized and economical switchgear is more and more recognized by users. Especially in the power transmission and distribution switchgear, circuit breakers, disconnectors, current transformers, voltage transformers, lightning arresters and other equipment can all be integrated into a switch cabinet, which greatly saves the operating cost of the equipment. As for indoor switchgear, how to perform secondary integration is the basis for miniaturization of the device. [0003] A circuit breaker is a switchgear, which includes a vacuum interrupter. The vacuum interrupter is equipped with moving and static contacts. The moving contact is connected with a condu...
