Description

[0002] Outdoor isolating switches are important equipment in the power system, which plays the role of isolating power supply and ensuring maintenance safety. Since they are exposed to the outdoor environment for a long time, they are easily affected by factors such as bad weather, dust, and pollutants. Therefore, they are usually equipped with protective covers to ensure the normal operation of the isolating switches. Existing outdoor isolating switch protective covers are usually made of ordinary plastic or rubber materials. There are many problems in actual application. For example, ordinary plastic materials have poor mechanical strength and weather resistance, and are prone to aging and deformation, while rubber materials are prone to bird feeding.

Among them, the signal processing circuit is used to amplify, filter and analog-to-digital conversion of the temperature signal collected by the temperature sensor 3, and the wireless communication module is used to transmit the processed temperature signal to the remote monitoring center.

[0027] As an optimization, this embodiment features a sleeve 12 on the outer wall of the protective cover 1, positioned corresponding to the heat dissipation hole 11. An integral socket 13 is positioned above the sleeve 12, with a slot provided within the socket 13, communicating with the inner cavity of the sleeve 12. Correspondingly, a plugboard 6, bonded to the dust sponge 2, is positioned within the slot. The top of the plugboard 6 is secured to the socket 13 via a connecting plate 61 and screws.

As an optimization, this embodiment features a rubber sealing strip (not shown) bonded around the lower port of the protective cover 1. During installation and use, a sealing strip is used to fit the outdoor disconnector, thereby improving sealing reliability and protective effect.

[0028] As a specific embodiment, the present invention utilizes a polycarbonate material and is manufactured through an integrated injection molding process to enhance the integrity of the protective cover 1. UV inhibitors and antioxidants are added to the polycarbonate material to enhance the weather resistance and aging resistance of the protective cover 1. As a specific embodiment, the present invention secures the temperature sensor 3 to the inner wall of the protective cover 1 through bonding to facilitate assembly and disassembly.

[0036] The working process of the protective device is as follows:

[0037] When the outdoor disconnector is operating normally, the temperature sensor monitors the operating temperature of the disconnector in real time and transmits the temperature signal to the signal processing circuit; after the signal processing circuit processes the temperature signal, it sends the temperature data to the remote monitoring center through the wireless communication module.

[0038] When the isolating switch experiences an abnormal temperature rise due to a fault or overload, the temperature detected by the temperature sensor exceeds the preset threshold. The signal processing circuit triggers an alarm, and a buzzer and flashing light emit audible and visual alarm signals. The wireless communication module transmits the alarm information to the remote monitoring center. Upon hearing the alarm signal, personnel can take timely measures, such as checking the operating status of the isolating switch and troubleshooting, to prevent equipment damage and safety accidents.
