Description
Technical field：
The present invention relates to the emergent heating means of the emergent heater of portable SF6 potting breakers.
Background technology：
Existing SF6 potting breakers are typically fitted with winter heater, prevent SF6 gases in the too low breaker of winter temperature
Liquefaction can not meet insulation and arc extinguishing requirement, and change the comparatively laborious peace, it is necessary to which professional shows up after heating locking apparatus damage
Dress, can not be reached in time for remote transformer station professional, in order to ensure the safe operation of equipment, once there are SF6 open circuits
The damage of device heater causes just to need power failure to handle during the low alarm of gas pressure, influences equipment power supply rate.
The content of the invention：
It is an object of the invention to provide a kind of emergent heating means of the emergent heater of portable SF6 potting breakers.
Above-mentioned purpose is realized by following technical scheme：
A kind of portable SF6 potting breakers are met an urgent need heater, and its composition includes：SF6 is switched, it is characterized in that：Described SF6
Switch center section is cylindrical shape, is cased with emergent heater, heater in described outside diameter of cylinder respectively, and described is emergent
There is silica-gel electrothermic plate inside heater, be silica gel sheath on the outside of described silica-gel electrothermic plate, there is silicon on described silica gel sheath
Glue groove, described silica-gel electrothermic plate are placed in described silica gel groove, are glued on the outside of described silica gel sheath by silica gel glue special
It is attached on insulation board, described insulation board is fixed on switch by buckle A, buckle B.
Described portable SF6 potting breakers are met an urgent need heater, and described insulation board is flexible material, described silicon
Glue electric hot plate is flexible material, and described buckle A and buckle B are spring steel material.
The emergent heating means of the emergent heater of described portable installing type SF6 potting breakers, its step are as follows：
（1）First, when being broken down during heater use, emergent heater is arranged among SF6 switches
On cylinder position, emergent heater can be arranged on SF6 by described emergent heater in the movement of cylinder, installation
The bottom of switch, and its is opening up；
（2）During reusing emergent heater, by power on to stabilized power source, described silicon can be made by wire
Glue electric hot plate heats, so as to recover the use of SF6 potting breakers switch；
（3）Described silica-gel electrothermic plate transfers heat to SF6 potting breakers switch, and switch internal gas pressure gos up, made
Electric power system is obtained to work on.
Beneficial effect：
1. the present invention is mainly to be to provide a kind of emergent heater of portable SF6 potting breakers, this Simple portable installing type
SF6 potting breakers are met an urgent need heater, and without professional person, installation is simple and convenient, on the basis of device structure is not changed,
By installing this device additional（Portable installing type SF6 potting breakers are met an urgent need heater）Return SF6 potting breakers gas pressure
Rise, avoid the phenomenon of the low alarm of gas pressure caused by SF6 breakers heater damages and the influence equipment power supply rate that has a power failure, be
The former heater that professional person handles damage gains time.
The present invention is by using in silica gel heating sheet insertion silica gel groove, embedded silica gel heating sheet and silica gel groove are fixed on
On the insulation board of 1mm thickness, the main body of heater is thus formed, then opening circle is made as heater in spring steel
Fixing device, it is simple and convenient so as to reach installation for the main body of heater to be fixed on to the tank body of potting breaker.
The heating material and insulating materials of the present invention uses flexible material, therefore can be directed to breaker of different shapes
Switch is effective, and the another present apparatus is simple in construction, and it is convenient to change, and lightly, and material is cheap, can prepare more, make provision against emergencies.
Brief description of the drawings：
Accompanying drawing 1 is the structure scheme of installation of the present invention.
Accompanying drawing 2 is the schematic cross-section in accompanying drawing 1.
