Description
Technical Field
The utility model relates to a vacuum electromagnetic starter technical field, concretely relates to mining flame proof and safe type dual supply vacuum electromagnetic starter of essence.
Background
The double-power-supply double-fan is a relatively efficient and safe fan forming mode, and the automatic switching device is a key device in the system and directly related to whether the whole system can safely operate or not. Therefore, the effectiveness and the reliability of the protection and control modes of the double-power double-fan automatic switching device are of great importance to the safe operation of the double-power double-fan automatic switching device. At present, once a main power supply and a standby power supply of an operated double-power-supply double-fan are powered off simultaneously or a main local ventilation system and a standby local ventilation system are failed simultaneously, corresponding protective measures are lacked, so that the safe operation of equipment and the life safety of underground workers are seriously influenced.
In addition, when the load electrical equipment has a fault and needs to be overhauled or lower equipment cables are moved, an operator can mistakenly operate the power isolation switch due to negligence, so that mistaken power transmission is caused, and an electric shock accident is caused.
SUMMERY OF THE UTILITY MODEL
The utility model provides a mining flame proof and safe type vacuum electromagnetic starter of essence has adopted intelligent protector, and the protection precision is high, and reaction rate is fast, has adopted manual isolator AND gate linkage shutting simultaneously, prevents that the maloperation from causing the accident.
The utility model adopts the technical scheme as follows:
the utility model provides a mining flame proof and intrinsically safe type dual supply vacuum electromagnetic starter, includes flame proof casing, mechanism of opening a door, intelligent electromagnetic starting control ware, operating button row, manual isolation reversing switch and drive connecting rod, the flame proof casing divide into four independent flame proof spaces in two main cavities and two wiring chambers, the wiring chamber is located the top of main cavity, the mechanism of opening a door is located the both sides of flame proof casing, intelligent electromagnetic starting control ware with operating button row installs on the door plant of flame proof casing, manual isolation reversing switch is located the both sides of flame proof casing.
The manual isolation reversing switch is connected with the door opening mechanism through the driving connecting rod.
The intelligent electromagnetic starting controller consists of a main control board, a microprocessor, a Chinese display, a current sensor, a voltage sensor and an RS485 networking communication interface.
The utility model discloses has positive effect:
the utility model adopts a double-door double-cavity independent structure, when the main machine loop stops working due to reasons of power failure, fault and the like, the standby machine is automatically cut in after time delay, and controls, starts and protects equipment such as a fan and the like, and the normal operation of the equipment such as the fan and the like is not influenced; and simultaneously, the utility model discloses a manual isolation change-over switch and the structure setting of the mechanism linkage shutting of opening the door, open manual isolation change-over switch when can making the maintenance of opening the door, prevent that the maloperation from leading to the occurence of failure.
