Case of control of the fan channel SAU-PPV-3,80-6,00
Application of cases of control of fans of smoke removal SAU-PPV-3,80-6,00
The case of control of fans of smoke removal SAU-PPV is realized on the basis of the power disconnector, the contactor and the electrothermal relay.
KOHTAKTOP represents the switching device allowing to operate currents in a circle of the main contacts, giving tension of management on the coil (actuator). Basic purpose of the actuator - remote start-up by direct connection to network of asynchronous engines.
The THERMAL RELAY in a set provides protection of engines against overloads of inadmissible duration. In this case the contactor is that actuator intended for control of the 3 phase engine. Thus, the case of control of fans of smoke removal SAU-PPV performs function of the contactor and the actuator.
The contactor with the coil of management on 380 V is the urgent decision for the industrial enterprises and builders as use of the coil on 380 V allows to avoid additional expenses at installation. Loading, in most cases, are asynchronous 3 phase engines on tension of 380 Century. In case of use of coils on 220 V it is necessary to use the fourth zero conductor, to carry out its installation in the scheme of management of the contactor that respectively leads to additional financial expenses and loss of working hours.
High degree of protection (IP54) allows to use a case of control of fans of smoke removal SAU-PPV at the industrial enterprises.
The main difference of SAU-PPV from SAU-SPV is existence of the power service disconnector of tension.
The case of control of fans of smoke removal SAU-PPV is made with the built-in disconnector of tension.
Cases of control of fans of smoke removal SAU-PPV are intended for control of channel fans, fans of the general and special purpose, and also smoke removal fans.
Design features of cases of control of fans of smoke removal SAU-PPV-3,80-6,00
The SCHEME of MANAGEMENT and universality of mass production allows to avoid mistakes at connection on the place and to reduce installation time which is limited only to accession of network.
The case of control of fans of smoke removal SAU-PPV works in the big range of temperatures from -40 °C to +55 °C, operation term not less than 10 years. Careful development of a design allowed to get a number of additional benefits and conveniences at installation and operation. For increase in safety the METAL CASE which is covered with qualitative powder paint that provides protection against corrosion is used. Besides, the case with grounding provides shielding of the electromagnetic fields arising when switching big currents. It causes protection of the equipment and safety of the person. The built-in disconnector of loading is also in addition provided that allows to increase safety of this equipment when carrying out service of the engine.
Connection of special contact of fire safety at which operation the case of control of fans of smoke removal SAU-PPV blocks operation of the electric motor of the fan is provided in a case of control of fans of smoke removal SAU-PPV. Connection of fire safety is obligatory at control of the fan.
Production of a case by the individual order is POSSIBLE.
