What are the safety control methods for dense bus ducts- CESKO

Release time:: 2021-03-15 Click count: 1345

  Dense busbar trunking is the most commonly used type of busbar laying.This busbar board made of steel plates,round steel,rivets or wooden wedges has a high iron content and a large area,which brings significant mechanical friction to the power system and causes operational resistance,seriously affecting the actual demand for system capacity.This fixed dense bus duct cannot prevent detachment due to the need for anchoring support,which can easily lead to heating and leakage accidents when various access methods cannot be changed or faults occur.

  Usually,safety verification and processing are carried out by controlling operating parameters.There are measurement methods such as thermal method,stress method,and slip test,but due to the limitations of the site and capacity,there are already traditional box shaped bus ducts placed on top.The compact structure of box trunking has the disadvantage of low friction,which makes it difficult to calculate the stress borne by the contacts using specified values.However,using contactors for control can easily generate arcs in certain areas,affecting safe operation.Generally,both methods are applied simultaneously.1.Friction method is a method of arranging three-phase windings through a single contact or sliding washer in the presence of a longitudinal slope,connecting the power supply,and manually or tactilely controlling the connection point to achieve heating or even leakage.

  2.Segmented control method:Segmented control is a safe control method for the sliding buttons of three-phase generator windings,winding joints,and the busbar itself.3.The sliding release mechanism method has a sliding coil in the middle of the busbar,which slides to support the connection between the phase wire and the live wire or block the closure of the coil or the connection between the phase wire and the neutral wire,thereby achieving the purpose of disconnecting the three-phase winding.In summary,it is found that box trunking technology is a relatively advanced technology that utilizes advanced sliding control as an anti detachment method.

  Its advantages include:easy processing,suitable for various layout methods,convenient and safe segmented fixation;A conductor can be used to apply force and motion to break the coil,with a large breaking range;Constant or variable values are controllable;It can achieve heat output and static disconnection operation.The safety issues of box trunking include:the fixed mechanism equipped with ultra thick steel plates is not easy to use and is prone to damage;The busbar protection measures are lagging behind,making it difficult to meet the requirements for normal operation;There are many situations where leakage is caused locally,and it is difficult to repair.

  Busway,also known as BUSWAY in English,refers to an electric highway,a supporting special transmission coil,and an auxiliary transmission system.MT is a globally recognized pioneering feature in the industry,highly recognized by the market,with extremely rich functions that enable voltage conversion of bus ducts when the electrical control voltage is below.After being equipped with MT,the electrical system becomes six wire harnesses with a stroke of 6mm,which can support voltage conversion of AC25%,DC24%,and AC16%.

  This means that once the bus duct power supply is disconnected,the backup line will be replaced,which not only ensures the safety of the backup line,but also helps to ensure the strength and stiffness of the mechanical structure.Bus duct is not only a comprehensive power transmission and distribution product,but also an important component of an independent power supply system.
