Abstract

The invention discloses a fuse monitoring bracket for external protection of a high-voltage capacitor. The included angle between the fixing plate and the mounting plate is an obtuse angle. The sensor mounting hole is installed on the mounting plate. The lower part of the mounting plate is provided with an upper clasp fastener. Features under hugging fastening. In the online monitoring method, the sensor is fixed on the monitoring bracket, and the signal transmitter is also fixed on the monitoring bracket at the same time. The signal transmitter is connected to the sensor, and the signal receiver and WEB server are set in the monitoring room. A monitoring bracket is installed on the base of the ejection tube. The angle of inclination of the mounting plate on the monitoring bracket cannot affect the performance of the fuse blowing. Fasteners and fastenings, hold the base of the paralyzed tube tightly. The invention has the advantages that no need to change the structure of the existing fuse tube, the universality is greatly improved, the state of the fuse tube can be accurately detected and the guardians can be notified in time.

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...
