Thyristor Switches
Thyristor switch mainly contains components as follows: Trigger circuit, thyristor, diode and ancillary circuit. Trigger circuit will judge whether it will output the control signal (DC12V) or not when voltage before and after zero crossing switching, so as to turn on or off. The trigger circuit can reliably ensure the output of the control signal. Radiator is mainly used for conducting heat and cooling through installed a switch which contains over- temperature protection and cooling fan controller, so as to provide the operation with a safe and good condition. Compared to other thyristor switch, this one has these advantages: no rush current, no touching noises; which is more suitable for those switching frequently occasions, such as lifts, cranes and welding machines. Application Tongdian Thyristor switch is in three-phase systems used to switch capacitors, and other switching device compared to the, the switch has no inrush current during switching, without exposure to noise and high switching frequency. These advantages are achieved by triggering circuits, thyristor, diode, and some auxiliary circuits. The switch is suitable for the occasion which changes the load quickly. Contact:

SVC Static Var Compensator
High- voltage static var compensator (SVC) is a shunt device of the flexible AC transmission system (FACTS) family using power electrics to control power flow and improve transient stability on power grid. Increase the ability of transmission and strengthen the damping of low frequency oscillation and suppress sub synchronous oscillation. in addition, SVC suppress the busbar voltage change that when cause by impact load, is better to transient voltage recover, improve the system voltage stability, when this device is applied to distribution network, such as electric railway, metallurgy and other industry, the users can control reactive power effectively, improve power factor, reduce voltage influence and harmonic interference that cause by nonlinear load, balance three phase load, improve power quality, efficiency and product quality, reduce the energy consumption. Static VAR Compensators (SVCs) can be customized to the specific needs of each customer. SVCs consist of multiple fixed or switched branches, at least one of which includes thyristors, and the combination of branches can vary greatly depending on the requirements. SVCs typically include a combination of at least two of the following given items (e.g. TCR/FC or TCR/TSC/FC): Thyristor Controlled Reactors (TCR) Thyristor Switched Capacitors (TSC) Harmonic Filters (FC) The most common topologies for static VAR compensators are: TCR/FC or TCR/TSC/FC. The main advantage of using a topology with TSC branches is reduced losses (by reducing filter size). Hitachi Energy's SVC control system can be used to control new or existing external shunt banks.

Chemical Industrial Pumps
Chemical industrial pumps Our chemical industrial pumps can be made of metal such as stainless steel, bronze, titanium alloy etc. materials or plastic such as PTFE/FEP/PVDF fluoroplastic, fiberglass reinforced plastic, polypropylene plastic etc. or metal lined with plastic. Chemical pumps are widely used to convey acid, alkali, salt etc. corrosive solution. Fluoroplastic pump is used to convey sulfuric acid and has the economic cost. Polypropylene and fluoroplastic pumps are suitable to convey hydrochloric acid. Fluoroplastic pump and titanium alloy pump is suitable to convey nitric acid. Stainless steel pump and fluoroplastic pump is suitable to convey acetic acid. Stainless steel and plastic pump can be used to convey alkali such as sodium hydroxide. Stainless steel SS316 pump and bronze centrifugal pump is suitable to convey sea water or brine etc. High temperature liquids pumping usually need the pumps equipped with cooling devices. When the liquid below 120 degree Celsius is conveyed, the pump is lubricated and cooled by the pumped liquids. CZ and IH Stainless steel chemical centrifugal pumps adopt suspension structure and the pumped liquids can be up 160 degree Celsius. IHF fluoroplastic liner pump can pump the liquid up to 200 degree Celsius. When the liquid at the temperature ranges from 120 degree Celsius to 300 degree Celsius is pumped, the pump cover should have cooling chamber and seal should also have cooling liquid with double end faces mechanical seal. CQB-G high temperature magnetic pump can pump the liquids below 280 degree Celsius. For the high temperature medium above 300℃, not only the pump head part needs to be cooled, but also the suspension bearing room should be provided with a cooling system. The pump structure is generally in the form of center support, and the mechanical seal is best to use metal bellows type. Minimum Order: 1 bags Contact:
