Abstract
The utility model relates to an overload protection device used for a piece of large-scale power equipment. The overload protection device used for the large-scale power equipment includes a current transformer, a shell, a current transducer, a thermal relay, a control circuit, a DCS device, an indicating green light, an alarm red light and a buzzer. According to the utility model, the alarm light is set to serve as a flickering alarm red light, so that visual indication is provided when equipment overload occurs and stability and reliability of the overload protection device are improved. The indication green lamp is an LED green lamp, so that indication during a normal operation process of the equipment can be given and power consumption can be reduced, and service lifetime of the overload protection device can be prolonged. According to the utility model, by arranging the alarm red light and the indication green light, convenience is made for an operator to know operation condition of the equipment directly and working efficiency is improved.
Description
Technical field
The utility model belongs to electric equipment protection device technique field, relates in particular to a kind of large scale electrical power unit overload protection arrangement.
Background technology
At present, usually there is overload phenomenon due to a variety of causes in the large scale electrical power unit using in industrial production, if processed not in time when generation or improper, very easily burns out motor, brings loss to production.Existing overload protection arrangement does not arrange indicator light, or a kind of indicator light is set, and is not easy to operator and gets information about the operation conditions of equipment.
Utility model content
The utility model for the warning indication that solves existing overload protection arrangement and exist not intuitively technical problem a kind of simple in structure, easy to install, large scale electrical power unit overload protection arrangement of increasing work efficiency is provided.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
The large scale electrical power unit overload protection arrangement of the utility model embodiment, this large scale electrical power unit overload protection arrangement comprises: current transformer, shell, current transducer, thermal relay, control circuit, DCS device, indication green light, warning red light, buzzer;
Current transformer is arranged on the top of shell, current transducer is arranged on the below of current transformer, DCS device is arranged on below current transducer, control circuit is arranged on the right side of DCS device, thermal relay is arranged on control circuit, indication green light is arranged on the below of DCS device, and warning red light is arranged on the right side of indication green light, and buzzer is arranged on the right side of warning red light.
The utility model can also adopt following technical measures:
Further, warning red light adopts the flicker red light of reporting to the police.
Further, indication green light adopts LED light.
Advantage and the good effect that the utlity model has are: due to the warning red light of the present utility model flicker red light that is set to report to the police, be conducive in the time of apparatus overload from visually indicating, improve stability and the reliability of overload protection arrangement; Indication green light is set to LED green light, is conducive to the indication in the time that equipment is normally worked and reduces energy consumption, the life-span that is conducive to improve overload protection arrangement.The operation conditions that convenient operation person is set gets information about equipment of the utility model warning red light and indication green light, has improved the efficiency of work.
