Problems solved by technology
However, most of the domestic technology is imported from abroad, and its transmission mode is basically two-stage transmission. This transmission mode has complex structure, poor reliability, high noise, especially belt wear, and difficult maintenance.
This brings inconvenience to the operation and maintenance of the high-voltage switch in the electrified railway traction substation

The invention provides an indoor-side-mounting electric operating device which comprises a frame, a panel assembly, a box cover, an electric accessory, a main driving part, a door sheet, an underframe, a motor support and a base plate, wherein the frame and the box cover are fixed by a butterfly nut, the frame is in bolted connection with the base plate through a connecting plate, the panel assembly is connected with the base plate through a bolt, the electric accessory is connected with the base plate thorough a bolt, the main driving part is connected with the base plate through a bolt, and the door sheet is connected with the frame through a bolt. By adopting a two-stage integral turbine worm reduction box side mount output mode, the indoor-side-mounting electric operating device stablely and reliably realizes deciliter operation of the high-tension switch. The indoor-side-mounting electric operating device has the advantages of running steadiness, convenience for installation and use, reliability for operation, convenience for maintenance and overhauling operations, attractive appearance and the like. According to the development speed of electrified railway in China, at least 1000 electric operating devices of the company can be sold per year, and the price of each electric operating device is 7 thousands, therefore, the annual sales revenue is 7 millions, and the economic benefit is extremely obvious. Due to the leading property in technology and the economic efficiency in price of the indoor-side-mounting electric operating device, the product is bound to create good social benefits.
Description
technical field [0001] The invention relates to an indoor electric operating device. Background technique [0002] The high-voltage switch electric operating device is a necessary product for the normal operation of the electrified railway traction substation system. It undertakes the task of opening and closing the high-voltage switch under the condition of no load, and is the main equipment to ensure the normal operation of the electrified railway traction substation system. It is mainly divided into two types: outdoor type and indoor type. Indoor operating devices are mainly used in traction substations. The main requirements for high-voltage switch operating devices are high operational reliability and accurate opening and closing positions. [0003] At present, most of the electric operating devices for vertically opening the high-voltage switch indoors in foreign countries adopt a two-stage transmission mode, one is a belt drive, and the other is a screw nut drive. F...
