Embodiment 1

[0024] like figure 1 As shown, the device includes a casing and an industrial hot air blower. The casing is equipped with a control module, a display module, an alarm generator module, a Flash information memory and a temperature sensor. The module includes a plurality of serial interfaces, and the display module, status indicator light, alarm generating module, Flash information memory and temperature sensor are respectively connected to the control module through the serial interface; the control module is connected to the industrial hot air blower through the serial interface.

[0025] In this embodiment, the control module adopts STM32F103 processor. The RX-8025 real-time clock is set in the control module. The temperature sensor adopts PT1000 temperature probe. The STM32F103 processor combines the functionality of the user interface with high-speed data connections, including two RS232 interfaces P10 and two RS485 interfaces P11 for data exchange with each module. The ...

Embodiment 2

[0034] like figure 2 As shown, the device includes a casing and an industrial hot air blower. The casing is equipped with a control module, a wireless communication module, a display module, an alarm generator module, a Flash information memory and a temperature sensor. The control module is equipped with an interface module. The interface module includes multiple The display module, the wireless communication module, the alarm generating module, the Flash information memory and the temperature sensor are respectively connected to the control module through the serial interface; the control module is connected to the industrial hot air blower through the serial interface. The shell is also provided with a voice playing module and a key module connected with the control module.

[0035] Through the button module, turn on the power to make the device start to work. When the detected temperature exceeds the threshold, the alarm generating module will alarm, and the alarm informa...

Abstract

The invention discloses a portable type SF6 gas cylinder heating system. A control module, a display module, an alarm generating module, a Flash information storage and a temperature sensor are arranged in a housing, wherein a state indicator lamp is arranged on the housing; an interface module is arranged on the control module; the heating module adopts an industrial hot-air blower; the control module is connected with the industrial hot-air blower through a serial interface; when the temperature is detected to be a normal temperature, a power supply of the industrial hot-air blower is opened by the control module to control the hot air blower to work, and the state indicator lamp gives green light; when the temperature is detected to exceed a line-crossing value, the alarm generating module alarms, the state indicator lamp gives red light, the red light is displayed on the display module, and the power supply of the industrial hot-air blower is switched off by the control module. According to the portable type SF6 gas cylinder heating system, constant control on temperature is realized by virtue of the control module, the industrial hot-air blower and the like, so that the gas charging efficiency is improved, the gas residual rate is reduced, and potential safety hazards can be avoided.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a portable SF6 cylinder heating system. Background technique [0002] Sulfur hexafluoride (SF6) has good insulation performance and arc extinguishing performance, and is widely used in power equipment, such as: circuit breakers, high-voltage transformers, gas-enclosed composite capacitors, high-voltage transmission lines, transformers, etc. 32 500kV substations, converter stations and UHV stations in a certain province all need to be operated and maintained. GIS140 bays (all of which are SF6 equipment) and 502 sets of equipment circuit breakers need to be operated and maintained. (all are SF6 equipment), 1689 current transformers (of which 1087 are SF6 equipment). SF6 gas insulated equipment has been widely used, which requires a lot of SF6 gas charging and gas replenishment during operation and maintenance. When the liquid SF6 in the gas cylinder is filled into the equipment, the...
