Description
Technical Field
The utility model relates to the technical field of load control, in particular to an automatic control system for overload of a small-capacity industrial distribution transformer.
Background
Two or more than two 10kV small-capacity distribution transformer parallel feeding industrial power systems have the common problem that the protection system is incomplete or even unprotected due to the distribution transformer, if one or more than two industrial power systems trip, all loads are superposed on other distribution transformers, and serious overload of the industrial power systems is caused to burn out the distribution transformers. Therefore, it is very critical to ensure that multiple distribution transformers are "co-supplied" (run simultaneously).
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a small-capacity industrial distribution transformer overload automatic control system which is high in safety, can immediately cut off all running loads when an auxiliary contact connected in series is tripped, and can timely judge and process tripping faults from the prompt of a tripping indicator lamp so as to ensure the safety of other distribution transformers.
In order to solve the technical problem, the scheme of the utility model is as follows:
the automatic control system of the overload of the small-capacity industrial distribution transformer is characterized in that: the system comprises a control loop, wherein a plurality of distribution transformers are arranged in the control loop and are arranged in the control loop in parallel; a circuit breaker is arranged on one side of the distribution transformer, the circuit breaker is connected with the distribution transformer in series, and an indicator lamp is arranged on one side of the circuit breaker and is electrically connected with the circuit breaker; the breaker is correspondingly provided with a breaker normally-open control contact, the breaker normally-open control contact is correspondingly arranged with the breaker, and the breaker normally-open control contact is arranged in series.
Specifically, the circuit breaker normally open control contact is a plurality of, and this circuit breaker normally open control contact establishes ties between the setting, and this circuit breaker normally open control contact inserts in the control circuit after establishing ties.
Specifically, the indicator light is a trip indicator light, and the indicator light is an alarm type trip indicator light.
Compared with the prior art, the utility model has the beneficial effects that:
the automatic control system for the overload of the small-capacity industrial distribution transformer connects the auxiliary normally open contacts of the circuit breakers corresponding to the distribution transformer in series and then connects the auxiliary normally open contacts to the control power supply loops of all loads, once one distribution transformer trips, the serially connected auxiliary contacts are disconnected, all operating loads can be immediately cut off, and tripping faults can be timely judged and processed through the prompt of the tripping indicator lamp, so that the safety of other distribution transformers is guaranteed.
