Description
Technical field
Transformer technical field of the present invention, more particularly to the transformer casing material of a kind of high temperature resistant and low temperature.
Background technology
Transformer is also known as instrument transformer, is the general designation of current transformer and voltage transformer, can become high voltage
Low-voltage, high current become low current, for measuring or protecting system, its function mainly by high voltage or high current in proportion
Be transformed into normal low voltage or standard small electric current, so as to realize the standardization of measuring instrumentss, protection equipment and automatic control equipment,
Miniaturization, while transformer may further be used to separate high-voltage system, to ensure the safety of the person and equipment.The shell master of transformer
Be used to encapsulate and protect transformer inside iron core and coil etc., therefore safe handling of the transformer casing to transformer
And service life has great importance.Current national standard for transformer casing temperature tolerance range -5~50
DEG C, the mechanical performance of transformer casing remains to meet normal use in the temperature range, when temperature exceedes the value range, then
Transformer security and service life can be produced and had a strong impact on.But under extreme working environment, such as in frigid zone
During area its environment temperature often be less than -5 DEG C, in addition transformer certain heating occurs when in use, as heat can not and
When shed the temperature of its transformer casing also can be more than 50 DEG C.Therefore the transformer of existing national standard is met, it is possible to nothing
Method tackles above-mentioned extreme operating environments.

Preferably, described toughener is butadiene.
Preferably, described fire retardant is bisphenol-A.
Preferably, described age resister is diphenyl carbonate.
The invention also discloses a kind of production technology of transformer casing material, comprise the following steps：First by weight will
Various raw materials are weighed, and are fed in double screw extruder and are granulated after mixing；The particle of acquisition is added in injection machine and is molded.
Preferably, the double screw extruder Zhong Ge areas temperature is as follows：One area's temperature is 200~230 DEG C, and two area's temperature are
230~260 DEG C, three area's temperature are 240~270 DEG C, and four area's temperature are 250~280 DEG C, and five area's temperature are 230~250 DEG C.
The beneficial effects of the invention are as follows：The high temperature resistant of the present invention and the transformer casing material of low temperature, its heat resistance and resistance to
Cold relatively strong, its tolerable temperature scope is -40 DEG C~100 DEG C, scope of -5 DEG C~50 DEG C more than national standard, be can be suitably used for each
Kind extreme operating environments.
