Leadership details

Product introduction:

Ky-zdgc-z handcart type mining general high-voltage vacuum power distribution device is mainly used in the power supply system of underground central substation, underground car yard, main ventilation duct and main ventilation duct power distribution chamber in underground gas-free and coal dust explosion place. It is used for power distribution, protection and control of three-phase AC 50Hz voltage 6kV or 10KV electric and gas equipment. It can also be used for direct starting or step-down starting of high-voltage motor for underground fan and water pump through dry reactance. It is also applicable to the control of coal mine ground substation, ventilator and winch, including metallurgy, chemical industry and other power supply systems.

Product structure:

1. The switch cabinet is indoor enclosed type with protection grade of IP40, which meets the provisions of gb12173 general electrical equipment for mining.

2. The basic structure is a thin-walled structure made of thin steel plate or aluminum zinc coated plate.

3. The switch cabinet is a rectangular box. The box is divided into handcart room, instrument room, cable room and bus room by partition in the middle of the box. The instrument room is equipped with all control and indication instruments. The handcart room is equipped with handcart, plug-in contact base and grounding plug; There are three conducting bars in the bus room, which are fixed on the box insulator as through bus; The cable room is equipped with bell mouth, varistor or resistance capacitance absorption device for cable introduction, and zero sequence current transformer can be installed according to different needs. The cable room is also equipped with small horn. Users can introduce control line to realize remote control. The lower part of the front of the box is the quick opening door of the hand abundant room, which is equipped with mechanical closing operation handle, circuit breaker, mechanical opening and closing indicator, mechanical opening button, etc.

4. Mechanical and electrical interlocking devices are installed in the switch cabinet to ensure the sequence of operation and "five prevention" safety, namely:

-When the circuit breaker is closed, it cannot move the test position from the working position or the working position from the test position.

-When the handcart is in the maintenance position or between the working position and the test position, the circuit breaker cannot be closed.

-The handcart door cannot be opened when the circuit breaker is closed.

5. The left and right side plates above the instrument room are provided with small bus connection windows, and the control small bus between cabinets can be easily connected with terminals, which is also convenient

Inspection and maintenance.

6. The switch cabinet has the advantages of simple operation and convenient maintenance. Open the door of the handcart room, put down the guide rail, press the trolley locking device by hand, and then pull the handcart by hand. The handcart can be pulled out from the box along the guide rail, and the main circuit electrical appliances on the handcart can be seen at a glance. When the front door is opened, the control and control instrument panel can be moved outside the box shell through the rotating shaft folding structure for inspection and maintenance. After opening the rear upper cover plate, the electrical equipment in the bus room and cable room can be repaired.

Performance characteristics:

The handcart of the same type has good interchangeability

The advanced technology of similar products from Germany is introduced, and the handcart adopts a central structure with good interchangeability.

Anti leakage measures

Special anti leakage measures are added in the design.

High strength housing

The shell is made of corrosion-resistant aluminum coated zinc plate material.

Strengthening sealing technology

Strengthened sealing technology shall be adopted at the door plate and sealing plate.

Drip proof measures at the top

Drip proof measures are set at the top.

Service conditions:

Ambient temperature: - 20 ℃ ~ + 40 ℃:

The altitude shall not exceed 1000m;

The relative humidity of the surrounding air shall not be greater than 95% (at 25 ℃);

Places without gas and coal dust explosion danger and violent vibration under the mine;

In an environment without gases and vapors sufficient to corrode metals and damage insulation;

A small amount of vertical dripping is allowed.
