Description
Technical field
This utility model belongs to the heat preservation technology field of outdoor high pressure equipment, more particularly to a kind of outdoor of severe cold area
The heat preservation technology field of SF6 choppers.
Background technology
At present, due to extremely frigid zones, Annual lowest climate temperature is reachable -40 DEG C, and with temperature reduce, SF6 gas pressures by
Gradually reduce, when temperature be less than -30 DEG C when, will there is liquefaction phenomenon in SF6 gases, so as to cause part transformer station because temperature compared with
It is low, SF6 gas liquefactions in SF6 high-tension switch gear arc extinguishings room and cause the event of circuit breaker lock action to occur, when serious
Even cause circuit breaker internal element to discharge shell, cause that device damage, the person are got an electric shock and chopper is bypassed the immediate leadership tripping operation large area
Power outage.The safe and stable operation of converting equipment and electrical network is had a strong impact on, heavy economic lossess are caused.
Utility model content
The purpose of this utility model is to provide a kind of outdoor SF6 choppers heater, it is intended to realize extremely frigid zones SF6
The normal work of chopper.
This utility model is intended employing the following technical solutions：
A kind of outdoor SF6 choppers heater includes air switch, vertoro, three groups of power lead butt joints,
Three silicone rubber heat tapes, three temperature sensor modules, DSP signal processing modules and terminal receiving device；
Further, two leading-out terminals of air switch connect two signal input parts of vertoro respectively, become repoussage
Stream device exports three groups of d. c. voltage signals, two terminals of every group of d. c. voltage signal respectively with one group of power lead butt joint
Two terminal connections of mains side, the load side of three groups of power lead butt joints connect the electricity of three silicone rubber heat tapes respectively
Source terminals, three temperature sensor modules are connected with DSP signal processing modules, and DSP signal processing modules are received with terminal again
Equipment connects；Three silicone rubber heat tapes are separately fixed at the outside of A phase arc extinguishing room housings, the outside of B phase arc extinguishing room housings
With the outside of C phase arc extinguishing room housings.
Further, this heater eliminates temperature controller, makes heater be changed to manually input from automatically engaging, prevent plus
Thermal can not come into operation because of cold weather blues.
Further, three silicone rubber heat tapes can be directly wound in the surface at heated position, install simple, peace
It is complete reliable.
Outdoor SF6 choppers heater of the present utility model, eliminates temperature controller, heater is changed from automatically engaging
For input manually, prevent heater from can not come into operation because of cold weather blues；The SF6 chopper heaters adopt silicone rubber
Electrical heating brings the temperature for improving the SF6 gases in chopper, makes SF6 gases not liquefy, it is ensured that SF6 choppers are in cold
The normal use in area, and silicone rubber heat tape has moisture resistance and insulating properties, so as to be effectively prevented personal electric shock thing
Therefore；220V alternating current power supplys are become 24V DC sources using vertoro by this utility model simultaneously, will not be to human body and equipment
Cause any harm.
Beneficial effect：This utility model stable performance, reliability are high, and feasibility is strong, easy to maintenance, easy to use.
