Device for quickly searching faults of voltage transformer

Abstract

The invention discloses a device for quickly searching faults of a voltage transformer. The bottom of the side cover plate is hinged to one side of the fixed shell plate; chutes are formed in the bottom of the fixed shell plate and the inner side of the side cover plate; a bottom plate of the frame is fixedly connected with a sliding seat; the bottom of the sliding base is slidably connected intothe sliding groove; a supporting frame is fixedly connected to the outer side of the frame, a rotating shaft is fixedly connected to the outer side of the supporting frame, a shaft sleeve is fixedly connected to one end of a linkage push rod, a supporting base is rotatably connected to the other end of the linkage push rod, a fusion tube bin is installed in a quick release fixing sleeve, one end of a drawing plug is inserted into the fixed shell plate, and an iron core is clamped in the frame. According to the device for quickly searching the faults of the voltage transformer, through the matched arrangement of the frame and the linkage push rod, under the pushing of the linkage push rod, the frame and the internal iron core can be separated from the clamping of the fixed shell plate and slide out along the sliding groove, so that the faults of the voltage transformer can be quickly checked, the touch of hands is avoided, and the safety is very good.

Description

technical field [0001] The invention relates to the technical field of electric equipment fault finding, in particular to a device for quickly finding faults of voltage transformers. Background technique [0002] In order to ensure the safety of the power system and prevent the expansion of accidents, the electromagnetic voltage transformer is generally taken out of operation and inspected by professional test personnel. When the electromagnetic voltage transformer is in long-term operation, the temperature will naturally rise. When the inter-turn insulation is poor, The insulation will also drop accordingly, forming a short circuit between turns, resulting in abnormal monitoring voltage. Capacitive voltage transformers will have capacitance changes, resulting in changes in the secondary monitoring voltage. When the test personnel arrived at the work site for the test, the temperature of the electromagnetic voltage transformer had dropped and the inter-turn insulation had b...
