Ким К., Карпова И. The electromagnetic acceleration of shells and missiles. Монография

The electrodynamic, electromagnetic and electrohydropulsive accelerating systems of objects are considered. The electrodynamic accelerators of electroconducting bodies are described. Their principle of action is based on the interaction of pulse magnetic field with currents induced in the accelerated body. To increase the pulse magnetic field we use the principle of electromagnetic cumulation of the initial magnetic field created by a superconducting coil. We give the concept of an electric acceleration of large objects having a weight of about 1000 kg till the speeds which are approaching to the space speeds. It is based on the combination of the conduction and induction principles of accelerating objects. It is shown that to increase the efficiency of a railgun we should divide the rail into separate electrically not connected segments and regenerate the energy of the magnetic field of a rail. We noticed in order to reduce losses in a rail it is reasonable to use the multilayered conductive mediums in the devices of current collection. For the induction accelerators with a continuous and step changing of the synchronous speed we consider a question about the control of inductor voltage at which the accelerator gets ideal properties. We investigated the question of the minimizing the length of a segmented accelerator. We consider the question of using the power characteristics of a spark discharge in liquid to accelerate the object.

Коммутационное реле ABB 2CCA704320R0001 16 А

Installation relays are electromagnetically operated miniature contactors in the standard DIN width of 18 mm. A reliable control system can be designed using these ABB Installation relays E297. They are used mainly in industrial plants but also in commercial and public buildings. As a rule, installation relays operated by means of a control switch (maintained contact) are installed where it is necessary to operate lighting, an air-conditioning system, a fan or suchlike. Installation relays are also referred to as monostable switching relays or 2-pole miniature contactors. The term "monostable" means that an on command has to be sent to the coil by means of a control switch (maintained operation) in order to excite the magnetic coil. The coil armature attracts and closes or opens the main contacts. The device remains in the on position for as long as the control voltage is applied to the coil. If the voltage flow to the coil is interrupted, the installation relay always returns to the neutral position (off pos

RUBETEK DOOR/WINDOW SENSOR RS-3215

This is a compact, battery-powered wireless radio device. The sensor is an additional component of security system that will help protect your home from unauthorized intrusion. It consists of two parts - a sensor with a reed switch and a magnet. If the reed switch is in the magnetic field range, the Sensor is closed. Opening is detected when the two components of the device are disconnected. In this case, a notification will be sent to your smartphone. Place it on doors, window sashes, cabinet or wardrobe drawers to always know what's going on at home. The Sensor can be used to create collaboration scripts with other devices. For example, to automatically turn off the air conditioner when opening a window in the room. The device is equipped with a tamper - you will receive a notification in case it is opened or torn off the surface. A Wi-Fi device supporting Rubetek RF 868 MHz sensors is required to add the device to the mobile app, receive notifications and create scripts.
