Abstract
The utility model discloses a transformer switching apparatus under a low-load state and the transformer switching apparatus comprises first and second transformers and first and second segments of buses. Wire inlet ends of the first and second transformers are respectively connected with an external power supply. Wire outlet ends of the first and second transformers are respectively connected with a switch and then respectively connected with the first and second segments of buses. A connection switch is connected between the first and second segments of buses. The transformer switching apparatus provided by the utility model has a simple structure and achieves a purpose of energy saving and consumption reduction. Under conditions of load and normal operation, transformer switching is realized, thereby being beneficial to chemical production stabilization. Operation of distribution devices is normal, thereby avoiding a problem of long-term power failure, achieving a production-unaffected purpose and having the meaning of energy saving and consumption reduction.
Description
Technical field
It is transformer bay switching device under a kind of low load condition that the utility model relates to.
Background technology
In the actual controller switching equipment that chemical industry, industrial and mining enterprises produce, the continuity particular importance of electricity consumption, once short power failure causes damage all can for production system equipment, and long-time outage impact will be larger, so when replacing controller switching equipment, be the most sensitive issue of chemical industry, industrial and mining enterprises.As everyone knows, along with the enforcement of conservation measures, the highly energy-consuming power transformer will progressively be eliminated, and changing, when cancelling transformer, certainly will affecting electricity consumption, bring loss to production.
The utility model content
The purpose of this utility model provides transformer bay switching device under a kind of low load condition, when the load of the first transformer hangs down, closed interconnection switch, (electric power incoming line) switch of the first transformer is disconnected, the load of first paragraph bus is transferred on the second segment bus, thereby stop using the first transformer, to reach energy-saving and cost-reducing purpose.
The technical solution of the utility model is as follows:
Transformer bay switching device under a kind of low load condition, include first and second transformer and first and second section bus, it is characterized in that: the end of incoming cables of described first and second transformer is external power supply respectively, behind the leading-out terminal difference connecting valve of first and second transformer, link to each other with first and second section bus respectively, be connected with interconnection switch between described first and second section bus.
Transformer bay switching device under the described low load condition is characterized in that: connect two motors and carbonization switchgear house by switch respectively on the described first paragraph bus.
Transformer bay switching device under the described low load condition is characterized in that: connect motor and methyl alcohol electric furnace by switch respectively on the described second segment bus.
The beneficial effects of the utility model:
The utility model is simple in structure, stable performance, easy for installation, easy to use, cheap, when the load of the first transformer hangs down, closed interconnection switch, (electric power incoming line) switch of the first transformer is disconnected, the load of first paragraph bus is transferred on the second segment bus, thereby stop using the first transformer, reached energy-saving and cost-reducing purpose, in the situation that there is the normal operation of load to realize the switching of transformer, be conducive to the stable of Chemical Manufacture, and the controller switching equipment normal operation, avoided the problem of long-time outage, reach the purpose that does not affect production, had again energy-saving and cost-reducing meaning simultaneously.
