Abstract
The double temperature control transformer consists of an iron core, a winding and two temperature sensors, wherein the winding is wound on a framework, the whole formed by winding the winding around the framework is arranged in the iron core, two temperature sensor holes are formed in the framework, the temperature sensors are arranged in the temperature sensor holes, and the two temperature sensors are respectively electrically connected with temperature controllers with different set temperatures. Compared with the prior art, the winding of the utility model is smoother and more attractive, and the two temperature controllers are protected by one alarm and one circuit, so that the overheat or ignition of the transformer can be avoided, the alarm signal can be sent out before the overheat of the transformer, and the disconnection of the control circuit can be avoided if the process is proper, thereby ensuring the working continuity of electric equipment.
Description
Technical Field
The utility model relates to a transformer, in particular to a double-temperature control transformer.
Background
It is known that in case of a transformer with an excessively large contact resistance at the joint connection failure; under the condition that electric equipment is short-circuited or overloaded; in the case of an arc or spark generated by a lightning strike on the transformer; under the conditions of increased temperature and the like of the eddy current caused by insulation damage of the iron core, the ignition phenomenon of the transformer is easy to occur, so that the design of the transformer capable of avoiding overheating or ignition is a technical problem to be solved at present.
Disclosure of Invention
The utility model aims to provide a transformer capable of avoiding overheating or ignition.
The technical scheme for solving the technical problems is as follows:
the double temperature control transformer consists of an iron core, a winding and two temperature sensors, wherein the winding is wound on a framework, the whole formed by winding the winding around the framework is arranged in the iron core, two temperature sensor holes are formed in the framework, the temperature sensors are arranged in the temperature sensor holes, and the two temperature sensors are respectively electrically connected with temperature controllers with different set temperatures. Therefore, the flatness of the transformer winding cannot be affected by the temperature sensor in the winding process (because the temperature sensor of the temperature control transformer in the prior art wraps the winding, the flatness of winding is poor), in addition, one of the two temperature controllers is an alarm temperature controller, the other is a circuit protection temperature controller, when the temperature of the transformer reaches the alarm temperature, the alarm temperature controller triggers an alarm device to remind operators that the temperature of the transformer is too high, corresponding measures are needed to be taken (the operation can not be stopped at the moment), but if the measures are improper, the temperature of the transformer continuously rises, and when the set temperature of the circuit protection temperature controller is reached, the circuit protection temperature controller is disconnected, and the whole control loop is disconnected to stop operation.
As a preferable mode of the present utility model, a base for mounting and fixing is provided at a lower portion of the iron core.
As a preferable scheme of the utility model, a frame-type wiring board is arranged at the upper part of the iron core, the inlet and outlet wires of the windings are connected through the frame-type wiring board, and the outlet wire end of the temperature controller is also connected with a control circuit of electric equipment through the frame-type wiring board.
Compared with the prior art, the winding of the utility model is smoother and more attractive, and the two temperature controllers are protected by one alarm and one circuit, so that the overheat or ignition of the transformer can be avoided, the alarm signal can be sent out before the overheat of the transformer, and the disconnection of the control circuit can be avoided if the process is proper, thereby ensuring the working continuity of electric equipment.
