Control and protection of counter-rotating local fan requirements

Before the start of the portable vacuum starter, the leakage protection circuit in the electronic protection device performs insulation detection on the insulated network of the controlled object. When the network insulation value is lower than the specified standard value, the implementation circuit of the electronic protection device is used. The operating power of the main circuit breaking element is cut off, and the breaking element of the main circuit cannot be closed, so that the portable vacuum starter achieves the leakage lock protection to the controlled object.

When the portable vacuum starter is used to control and protect the local fan, when the local fan starts, a signal is input to the wind power delay lock protection circuit of the portable vacuum starter, and the time-delay portable vacuum starter electronic protector Output a signal to the power switch of the mining face; the power switch of the mining face can only start after receiving this signal and send power to the other electrical equipment of the mining face; conversely, if the local fan fails While the portable vacuum starter protects and stops the local fan, the portable vacuum starter outputs a signal to the power switch of the mining work face; the power switch of the work face is cut off, and other electrical equipment of the mining work face is made. All blackouts occurred in an instant, and the implementation of the coal mine safety regulations requires that the power transmission must be aired first, and the stoppage of wind power must be requested.

When the portable vacuum starter is used to control and protect the water pump, the probe is put into the water, and the water pump can be automatically turned on and waterlessly shut down.

The main technical parameters When the power supply voltage is not lower than 85% of the rated value, the portable vacuum starter should be able to work reliably; when the working voltage exceeds 10% of the rated value, the portable vacuum starter should be allowed to work for a short time.

Phase-failure protection performance scale current multiple action time t initial state reset mode two-phase is 1105; a phase multiple scale current starts automatically resets wind power delay lockout protection performance action time, continuous adjustable delivery power supply within 10min vacuum portable start When the device controls the water pump, it can realize automatic shutdown without water and automatic start protection with water. The action time is less than 2 seconds. In particular, when two vacuum portable starters are used to control a counter-rotating local fan, the requirements for controlling and protecting the counter-rotating local fan can be met without any modification.

1. Bucket management: automatic production is adopted from the link of picking up the bucket. Only the barrels of the same specifications and models need to be neatly placed in the designated position.2, filling: automatic filling device is equipped with automatic meter, according to the preset standard, the amount of the filling nozzle will be directly filled to the material sent to the packaging barrel.The whole process is accurate and fast, and will not cause waste of materials, not to mention environmental pollution.The loaded barrel will be transferred to the next link through the power track.3. The capping and capping filled buckets are accurately sent to the automatic capping machine. The capping machine, through the manipulator, absorbs a bucket cap each time and places it accurately on the filled bucket.4, automatic stacking: the filling of the packaging barrel after sealing packaging, transfer to the automatic stacking machine.Automatic stack machine through the professional manipulator, will be filled with packaging barrel accurately absorb and placed in the set tray.When the number of barrels in the pallet reaches the specified number, the manipulator will automatically transport the pallet placed in the bucket to the specified location.
