Abstract

The invention discloses a fuse monitoring bracket for the external protection of a high-voltage capacitor. An included angle formed between a fixed plate and an installation plate is an obtuse angle. The installation plate is provided with a sensor installation hole. The lower part of the installation plate is provided with an upper cohesion fastener. The lower part of the fixed plate is provided with a lower cohesion fastener. The on-line monitoring method comprises the steps of fixing a sensor onto the monitoring bracket, and fixing a signal emitter onto the monitoring bracket at the same time, connecting the signal emitter with the sensor, arranging a signal receiver and a web server in a monitoring computer room, installing one monitoring bracket on the ejection tube base of each cartridge fuse, and tightly holding the ejection tube base through wrenching the upper cohesion fastener and the lower cohesion fastener, wherein the fuse fusing performance is not influenced by the inclined angle of the installation plate on the monitoring bracket and the cartridge fuse can be in contact with the sensor on the monitoring bracket after the fuse fusing process. According to the technical scheme of the invention, the structure of an existing cartridge fuse is not changed at all, so that the universality is greatly improved. Meanwhile, the state of the cartridge fuse can be accurately detected and timely told to supervisors.

Description

technical field [0001] The invention relates to a fuse monitoring bracket for external protection of a high-voltage capacitor and an online monitoring method. Background technique [0002] At present, most of the high-voltage shunt capacitors for reactive power compensation of 35 kV and below in the power grid are indoor complete sets of device (cabinet) structures or outdoor structure layouts. According to the size of the compensation capacity, generally several single capacitors are combined into a set. . A single capacitor on a complete capacitor device (cabinet) generally uses an external protection fuse to protect the internal fault of the capacitor. Most other capacitor banks installed outdoors also use this kind of external fuse to protect a single capacitor. This kind of fuse is usually called a fuse for external protection of capacitors or a spray fuse (formerly known as a spray fuse), and it is also called a special ejection fuse for capacitors. [0003] The fun...
