TD28 type and other potential coupling terminal box
Summary
And other potential terminal box is to protect the main building, water gas metal pipeline, heating and cooling, cooling system, building metal parts and other parts of the connection, to meet the requirements of the specification of the contact voltage is less than 50V. Is an important part of modern building electrical appliances, is widely used in high-rise buildings.
Effect
1 the role of the total and other potential coupling is to reduce the contact voltage and the potential difference between the different metal parts of the indirect contact voltage and the risk of different metal parts.
2 auxiliary, such as the role of the potential connection: the two conductive part of the direct contact with the wire, so that the fault contact voltage to the contact voltage limit below. Power network impedance, so that the power supply time is too long, can not meet the requirements of anti electric shock; in order to meet the special requirements of the bath, swimming pool, hospital operation room and other places to prevent electric shock; self TN system with a power supply of fixed and mobile two electrical equipment, and fixed equipment to protect the electrical power off time can not meet the requirements of mobile anti electric shock.
3. Local equipotential: when the need to do each auxiliary equipotential coherence is within the scope of a local place, through local equipotential bonding terminal plate will be the following part communicated with each other, to easily realize the localized within a plurality of auxiliary equipotential connection. It is called a local equipotential bonding.
Application suggestion
1 can not be sealed in the wall;
2 can not be used in china;
3 not to give up
Concrete practice
In the bathroom will be a variety of metal pipes, structural elements (including concrete slabs in the bar) and into the bathroom, the line of sight, with no less than 4mm2 of the copper core, through the potential connection terminal box is connected with each other. And other potential connecting wires in the floor or wall in the dark when to wear plastic pipe protection, its purpose is to change the wire easy. The resistance between the terminals of the metal pipe and the metal pipe in the connection range is less than 5. Metal pipe in the bathroom is generally not required to add a cross connection, if found to lead to bad, should be cross connected. When the water pipe in the bathroom is a plastic pipe or plastic metal tube, and other potential cross connection can be connected to the tap water faucet; the use of metal pipes, cross connect directly to the water pipe. The toilet sewage pipe and between the water pipe is blocked, so the sewage pipe shall be equipotential bonding, connected to the drain pipe.
