Example Embodiment

[0017] Example 1:

[0018] A portable SF6 tank circuit breaker emergency heating device, which consists of: SF6 switch 1. The middle part of the SF6 switch is cylindrical, and the outer diameter of the cylinder is covered with an emergency heating device 2 and a heating device. 3. The emergency heating device has a silicone electric heating plate 4 inside, and the outside of the silicone electric heating plate is a silicone sleeve 6, the silicone sleeve has a silicone groove, and the silicone electric heating plate is placed in the silicone groove Inside, the outside of the silicone sleeve is pasted on the insulating plate 7 with special glue for silicone, and the insulating plate is fixed on the switch by the buckle A8 and the buckle B9.

Example Embodiment

[0019] Example 2:

[0020] According to the portable SF6 tank circuit breaker emergency heating device of embodiment 1, the insulating plate is made of soft material, the silicone heating plate is made of soft material, and the buckle A and the buckle B are springs Steel material.

Example Embodiment

[0021] Example 3:

[0022] According to the emergency heating method of the portable SF6 tank circuit breaker emergency heating device described in embodiment 2, the steps are as follows:

[0023] (1) First, when the heating device fails during use, install the emergency heating device on the cylinder position in the middle of the SF6 switch. The emergency heating device can move in the cylinder. When installing, the emergency heating device Install on the lower part of the SF6 switch with its opening facing upwards:

[0024] (2) In the process of using the emergency heating device again, the power supply is connected to the stable power supply, and the silicone electric heating plate can be heated through the wire, so as to restore the use of the SF6 tank circuit breaker switch;

[0025] (3) The silicone heating plate transfers heat to the SF6 tank circuit breaker switch, and the gas pressure inside the switch rises, so that the power supply system continues to work.

Abstract

The invention relates to an emergency heating method of an emergency heating device for a portable SF6 tank type circuit breaker. At present, the existing SF6 tank type circuit breaker usually has a heating device for winter. Once the alarm is raised for low gas pressure due to the damage to the heating device, power outage will be required, and power supply to equipment will be affected. The emergency heating device includes an SF6 switch (1) of which the middle part is cylindrical. The outer diameter of the cylinder is sleeved with an emergency heating device (2) and a heating device (3). The emergency heating device is internally provided with a silica gel electric heating plate (4). A silica gel sleeve (6) is arranged outside the silica gel electric heating plate. The silica gel sleeveis provided with a silica gel slot. The silica gel electric heating plate is placed in the silica gel slot. The outer side of the silica gel sleeve is pasted onto an insulating plate (7) by special glue water for silica gel. The insulating plate is fixed to the switch through a buckle A (8) and a buckle B (9). The emergency heating method is used in an emergency heating device for a portable SF6tank type circuit breaker.

Description

Technical field: [0001] The invention relates to an emergency heating method of a portable SF6 tank type circuit breaker emergency heating device. Background technique: [0002] Existing SF6 tank circuit breakers are generally equipped with winter heating devices to prevent the liquefaction of SF6 gas in the circuit breaker in winter when the temperature is too low to meet the insulation and arc extinguishing requirements. However, it is cumbersome to replace the heating device after it is damaged, and requires professionals to install it on site. For remote substation professionals who cannot arrive in time, in order to ensure the safe operation of the equipment, once the SF6 circuit breaker heating device is damaged and the gas pressure is low, it needs to be shut down, which will affect the power supply rate of the equipment. Invention content: [0003] The purpose of the present invention is to provide an emergency heating method of a portable SF6 tank circuit breaker ...
