Problems solved by technology

[0003] At present, the data collection method of switchgear in the prior art is fixed-point, so it is impossible to know the data value of each position inside the power distribution cabinet. Long-term data detection and collection at a certain place cannot obtain accurate data, which makes the detection accuracy In general, for this purpose, we propose a data collection device for switchgear sensors

Abstract

The invention discloses a data collection device for a switch cabinet sensor, relates to the technical field of data detection and collection, solves the problem of inaccurate data collection during fixed-point detection, and comprises fixed blocks fixed at the top and the bottom of two sides of a switch cabinet, and sealing parts are installed at the positions, corresponding to detection ports, of the inner side of the switch cabinet. An adjusting screw rod is rotatably inserted between the two fixing blocks on the same side, the outer sides of the two adjusting screw rods are sleeved with a U-shaped plate in a threaded mode, a driving motor is fixed to the outer side of the switch cabinet, the output end of the driving motor is fixed to the outer end of one adjusting screw rod, linkage pieces are fixed to the bottoms of the two adjusting screw rods, and a moving opening is formed in the U-shaped plate; according to the invention, the U-shaped plate moving on the adjusting screw rod is designed, and the data collection mechanism is designed in the U-shaped plate, so that the temperature detection of all parts in the switch cabinet is satisfied, and the accuracy of the detection data is improved.

Description

technical field [0001] The invention relates to the technical field of data detection and collection, in particular to a data collection device for switchgear sensors. Background technique [0002] The power switchgear is an important equipment responsible for load distribution in the power system. Due to the large load current, some switchgears can pass through a current of up to 4000A for a long time, while the contact position of the contacts (plugs) in the cabinet is offset, the dynamic and static contact springs are loose, and the material Bad and other factors will lead to poor contact of the contacts, resulting in severe heat. According to the relevant requirements of the national standard GB763-1990 "Heating of AC high-voltage electrical appliances during long-term work", the maximum allowable temperature of bare copper or bare copper alloy contacts in a 10kV switch cabinet is 75°C, and the maximum temperature of the equipment joints in the cabinet must not exceed T...
