AMS INDUSTRIEL electrical components German AMS INDUSTRIEL models AMS INDUSTRIEL prices

AMS INDUSTRIEL electrical components utilize the high conductivity and fluidity of mercury to control the opening and closing of electrical circuits. They consist of a glass tube, mercury, fixed electrodes, lead wires, etc. After evacuating the air from the tube, it is sealed with various gases. They are suitable for environments with dust, oil, water vapor, and corrosive gases, and can also serve as explosion-proof switches in areas with explosive gases. Due to the high surface tension and specific gravity of the mercury inside the tube, along with its fluidity, even a slight tilt of the glass tube causes the mercury's position to change immediately, making surface contact with the electrodes, thus enabling the switching of high AC and DC currents. Additionally, this type of switch features a lifespan of several million operations at rated current, compact size, high sensitivity, no mechanical noise, and low cost, making it widely used as an automatic control switch.

AMS INDUSTRIEL electrical components composition

Internal accessories of circuit breakers: Auxiliary contacts are mechanically linked to the main circuit breaking/making mechanism of the circuit breaker, primarily used to indicate the open/closed status of the circuit breaker. Connected in the control circuit of the circuit breaker, they control or interlock related electrical devices through the breaking/making action of the circuit breaker. Alarm contacts are used for accident alarms in circuit breakers. These contacts only operate after the circuit breaker trips and opens, primarily when the load experiences faults such as overload, short circuit, or undervoltage, causing free tripping. The alarm contact changes from its normally open position to a closed position, activating indicator lights, bells, buzzers, etc., in the auxiliary circuit to display or alert the fault trip status of the circuit breaker. Since the probability of free tripping due to load faults is relatively low. Shunt release: A shunt release is a tripping device energized by a voltage source, independent of the main circuit voltage. It is an accessory for remote opening operation. When the power supply voltage is any value between 70% and 110% of the rated control power supply voltage, the circuit breaker can reliably open. The shunt release operates on a short-time duty cycle; the coil energization time generally must not exceed 5S, otherwise the coil will burn out. To prevent coil burnout in molded case circuit breakers, a microswitch is connected in series with the shunt release coil. When the shunt release engages via the armature, the microswitch changes from normally closed to normally open, cutting off the control circuit power to the shunt release. Even if the button is manually held down, the shunt coil will not be re-energized, preventing coil damage. After the circuit breaker is reset and closed, the microswitch returns to the normally closed position. Undervoltage release: An undervoltage release is a tripping device that causes the circuit breaker to open with or without delay when its terminal voltage drops to a specified range. Under thermal conditions, it must ensure reliable closing of the circuit breaker. Therefore, when a certain voltage drop occurs in the protected circuit's power supply, it automatically opens the circuit breaker to cut off power, protecting downstream loads or electrical equipment from undervoltage damage. During use, the undervoltage release coil is connected to the power side of the circuit breaker; the circuit breaker can only close after the undervoltage release is energized.

Sensors generally consist of four parts: sensitive elements, conversion elements, signal conditioning circuits, and auxiliary power supplies. Sensitive elements directly sense the measured quantity and output physical signals with a definite relationship to the measured quantity; conversion elements convert the physical signals from the sensitive elements into electrical signals; signal conditioning circuits are responsible for amplifying and modulating the electrical signals from the conversion elements; conversion elements and signal conditioning circuits generally require auxiliary power supplies.

AMS INDUSTRIEL electrical components applications

Wire and cable products used in power systems mainly include bare overhead conductors, busbars (bus ducts), power cables (plastic-insulated cables, oil-paper insulated cables (largely replaced by plastic power cables), rubber-sheathed cables, overhead insulated cables), branch cables (replacing some busbars), magnet wires, and electrical equipment wires and cables for power equipment. Wire and cable products used in information transmission systems mainly include telephone cables, TV cables, electronic wires, RF cables, fiber optic cables, data cables, magnet wires, power communication cables, or other composite cables. Except for bare overhead conductors, almost all other products in this category have applications, but mainly power cables, magnet wires, data cables, and instrument cables.
