Embodiment Construction

[0025] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0026] illustrate: figure 1 , figure 2 , Figure 4 and Figure 6 The direction of the arrow in is the linear motion direction of the intermediate element 100 .

[0027] Such as figure 1 As shown, according to the embodiment of the present invention, the indicating device is used to indicate the working position of the high-voltage switch. The high-voltage switch includes a linearly moving intermediate element 100. The indicating device includes a rotating shaft 10, a pointer 20, a return mechanism and a motion conversion mechanism. The rotation axis of the rotating shaft 10 is parallel to the moving direction of the intermediate element 100; the pointer 20 is used to indicate the working positi...

Abstract

The invention provides an indication device. The indication device is used for indicating the work position of a high-voltage switch. The high-voltage switch comprises a middle element which moves linearly, the indication device comprises a rotary shaft of which the rotation axis is parallel with the moving direction of the middle element, a pointer for indicating the work position, a reset mechanism directly or indirectly connected with the rotary shaft for resetting the pointer to the initial work position, and an motion conversion mechanism connected between the rotary shaft and the middle element for converting the linear motion of the middle element into the rotation of the rotary shaft, wherein the pointer is fixedly connected to a first end part of the rotary shaft. By applying the indication device, the technical problem that no mode in which the linear motion of the middle element is directly adopted to realize the swing of the pointer to indicate the position exists in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of high voltage switchgear, in particular to an indicating device. Background technique [0002] High-voltage switches refer to equipment used for on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption, mainly including high-voltage circuit breakers, high-voltage isolating switches and grounding switches, high-voltage load switches, high-voltage Several categories such as automatic reclosing and sectionalizers and high-voltage switchgear. The high-voltage switch manufacturing industry is an important part of the power transmission and transformation equipment manufacturing industry, and occupies a very important position in the entire power industry. Section 5.12 of GB11022-2011 "Public Technical Requirements for High-Voltage Switchgear and Control Equipment Standards" clearly stipulates that "when the contacts are not visible, a ...
