Substation transformer for heating concrete KTPTO-80
Technical parameters
Service conditions: the top working and effective value of temperature
of air makes accordingly plus 10 °С and 0 °С, the bottom working value
of temperature of air makes a minus 40 incidentally - to a minus 45 °С.
Into the delivery complete set enter: the power transformer and the case of management established on a sled; the description and maintenance instruction КТПТО; the passport on КТПТО; the description and the maintenance instruction of the power transformer; the passport of the power transformer. One of directions of the accelerated building with erection of monolithic ferro-concrete designs is the technology of concreting with application of thermal methods of acceleration твердения concrete. Твердение concrete at low temperatures of air it is essentially slowed down, and at its temperatures more low +5°С concrete is necessary for warming up. Now in the absence of reliable and inexpensive chemical additives - accelerators твердения concrete - the technology of winter concreting basically is based on application of a method of warming up of concrete by means of special transformers of warming up of concrete with its subsequent keeping before achievement of standard values critical and распалубочной durabilities. Such technology is, in effect, ресурсосберегающей as by additional power inputs possibility is reached:
One of the most economic (from the point of view of energy expenses) ways of electroheat treatment of concrete is the way of electrowarming up (warming up of concrete by means of substations KTPTO-TSZPB) or electrode warming up, i.e. concrete inclusion in an electric chain as though as a conductor. Thus electric energy turns in thermal directly in the concrete that reduces to a loss minimum. Depending on capacity of an electric current it is possible to heat up concrete to temperature of 100 degrees, and for any time interval - from several minutes till several o'clock. Thus, there were ample opportunities to choose optimum modes of heating of concrete and thanks to it to provide high efficiency of technological lines and monolithic building. |
