Abstract

The invention discloses a circuit transformer bank non-electricity protection device and a system. The circuit transformer bank non-electricity protection device comprises a non-electricity protection unit, a remote breaking unit, an interface unit, and a control unit, wherein the non-electricity protection unit is used for transformer non-electricity protection; the remote breaking unit is used for sending and receiving a remote breaking instruction; the interface unit is used for connection between devices; and the control unit is connected with the non-electricity protection unit, the remote breaking unit and the interface unit respectively for controlling the non-electricity protection unit, the remote breaking unit and the interface unit. Thus, the problems that outlet time for a circuit transformer bank non-electricity protection remote breaking opposite-side circuit breaker is too long and reliability is poor can be solved, and effects of improving quickness and reliability of circuit transformer bank non-electricity protection are achieved.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a line transformer group non-electricity protection device and system. Background technique [0002] Line transformer group wiring refers to the direct connection between the line and the transformer, such as figure 1 As shown in the industrial and mining enterprise process equipment substation line transformer group wiring, there is a circuit breaker at both ends of the line transformer group, namely circuit breaker 02 (circuit breaker on the line side) and circuit breaker 01 (circuit breaker on the low voltage side of transformer 03) , and no circuit breaker is set at the connection between the line and the transformer 03 (the high voltage side of the transformer 03). The main common features of transformer group wiring for primary equipment lines in industrial and mining enterprises are: first, the power supply distance is within 2km, that is, the power supply line is not more t...
