Abstract
The utility model discloses intelligent measurement-protection specialized equipment used for a 35 kV main line. The equipment comprises a cross beam, a double-station isolated grounding switch fixed on the top surface of the cross beam, and an electric mechanism and a plug-in type lightning arrester which are fixed on the bottom surface of the cross beam. A shell of the double-station isolated grounding switch is provided with a plug-in type outdoor voltage transformer. The bottom part of the outdoor voltage transformer is fixed on one side of the cross beam through a bracing frame. The double-station isolated grounding switch is of a three-phase split cabinet type, and the three cabinets are connected through an air passage. One end of the air passage is connected and provided with a pressure detection meter having a teletransmission function. The equipment can be applied to a voltage measurement-protection interval on two segments of a bus of a single-bus segmenting project of a 35 kV station, and also can be used for a line side. The switch is small in size so that the floor area is enabled to be small. The equipment is digitalized and intelligentized, and has controllable protection and measurement functions.
Description
Technical field
The utility model relates to a kind of electric equipment of the intelligences combination for the 35KV outdoor substation.
Background technology
Existing 35kV survey guarantor's combined electrical apparatus primary equipment volume and installing space are larger, and the device space of mainly being isolated ground connection affects.The installing space of voltage transformer and lightning arrester and space for maintenance, also greatly restricted the process of device miniaturization.
Summary of the invention
The problems referred to above that exist for solving existing equipment, the utility model provides a kind of survey for the 35kV main line to protect special equipment, its technical scheme of taking is: comprise crossbeam, be fixed on two station isolation grounding switchs on the crossbeam end face, and be separately fixed at motor drive mechanism and the plug-in type lightning arrester on the crossbeam bottom surface, the housing of two station isolation grounding switchs is provided with the plug-in type outdoor voltage transformer, a side of crossbeam is fixed in the bottom of outdoor voltage transformer by bracing frame, two station isolation grounding switchs are that three-phase separate is box, between them, by gas circuit, connect, one end of gas circuit connects the pressure detecting table of tool transporting function.
The utility model adopts the box isolation of three-phase separate ground connection two station structures, dwindled installing space, save gas usage, adopt brand-new outdoor plug-in type that voltage transformer is installed, and plug-in type lightning arrester, a high-pressure side all is sealed in the SF6 air chamber, and secondary terminals adopts outdoor structure to be convenient to wiring and maintenance.The utility model can apply to the 35kV voltage of standing on two sections buses of single mother partition projects and survey and protect interval, also can be used for line side, and the volume of switch is small and exquisite, makes floor space little; The equipment prefabrication, make installation period short, the Whole Equipment convenient transportation.
