Novel observation window for gas-insulated switchgear

Abstract

The invention discloses a novel observation window for a gas-insulated switchgear. The novel observation window comprises a perspective window, a light source device and a monitoring device, the perspective window is installed in the gas-insulated switchgear, the on-off state in the gas-insulated switchgear is observed through the perspective window and the monitoring device, and the light source device adjusts the brightness of the gas-insulated switchgear and the brightness of the monitoring environment. According to the invention, the viewing angle is amplified by adopting an optical imaging principle, all visual fields of the three phases and three states of longitudinally arranged switches are satisfied by a small viewing port. According to the invention, the source of a light source inside the gas-insulated switchgear and the observation window are integrated into one viewing port, so that the number of sealed holes of the gas-insulated switchgear is reduced, the light source device is externally assembled, and can be replaced arbitrarily, the situation that secondary component damage possibly causes failed observation during long-term switch operation. An installation frame is provided with a positioning block, a support is provided with a positioning cavity, the positioning block and the positioning cavity are installed in a matched mode, and the situation that the illumination effect is affected due to relative rotation of the installation frame can be avoided.

Description

technical field [0001] The invention belongs to the field of inflatable full-insulation and full-sealing ring network cabinets, and relates to a novel observation window for inflatable cabinets. Background technique [0002] Nowadays, inflatable fully insulated and fully sealed ring network cabinets and solid cabinet insulated ring network cabinets are widely used in the field of power grid power distribution. Since the switches are all in the sealed stainless steel inflatable cabinet or epoxy resin inflatable cabinet, and the inflatable cabinet is opaque, The switch status cannot be directly observed. In some special power consumption situations, in order to ensure the safety of power consumption, the user hopes to directly observe the position status of the main circuit switch. [0003] In addition, due to the compact structure and small size of the inflatable ring main unit and the solid insulation cabinet, the existing observation windows cannot fully observe the three p...
