Cariboni electrical components Germany Cariboni model Cariboni price

Cariboni electrical components are tools that can accurately determine and measure temperature, divided into pointer thermometers and digital thermometers. Depending on the temperature-sensing substance used and the temperature measurement range, there are kerosene thermometers, alcohol thermometers, mercury thermometers, gas thermometers, resistance thermometers, thermocouple thermometers, radiation thermometers and optical pyrometers, bimetallic thermometers, etc. Digital thermometers can accurately determine and measure temperature, displaying it digitally rather than with a pointer or mercury. Hence they are called digital thermometers or digital temperature gauges.

Cariboni electrical component composition

A diode is formed by a PN junction plus corresponding electrode leads and package encapsulation. Using different doping processes, through diffusion, P-type semiconductor and N-type semiconductor are fabricated on the same semiconductor (usually silicon or germanium) substrate, forming a space charge region at their interface called the PN junction. The electrode drawn from the P region is called the anode, and the electrode drawn from the N region is called the cathode. Due to the unidirectional conductivity of the PN junction, when the diode conducts, current flows from the anode through the interior of the tube to the cathode. A diode has two electrodes; the electrode drawn from the P region is the positive terminal, also called the anode; the electrode drawn from the N region is the negative terminal, also called the cathode.

Cariboni electrical component functions

The main purposes of disconnect switches (knife switches) are: 1, to isolate the power supply, disconnecting high-voltage maintenance equipment from live equipment, creating a clearly visible break point between them. 2, disconnect switches cooperate with circuit breakers to perform switching operations as required by system operating modes, changing the system wiring configuration. 3, to connect or disconnect low-current circuits. Disconnect switches can perform the following operations: make and break bypass currents of closed-loop switches; make and break grounding connections at transformer neutral points, but if an arc-suppression coil is connected to the neutral point, operation is only permitted when the system is fault-free; make and break voltage transformers and surge arresters; make and break capacitive currents of busbars and equipment directly connected to busbars; make and break no-load lines with capacitive current not exceeding 5 amperes; triple-pole disconnect switches can make and break loads with voltage at 10 kilovolts and below, and current below 19 amperes, etc. When operating disconnect switches, note that when energizing a line, first close the busbar-side disconnect switch, then close the line-side disconnect switch, and finally close the circuit breaker. When de-energizing a line, first open the circuit breaker, then open the disconnect switch. Do not make or break high-voltage disconnect switches under load.

Cariboni electrical component parameters

1. Nominal varistor voltage: refers to the voltage value across the varistor when a pulse current of specified duration passes through it. 2. Voltage ratio: refers to the ratio of the voltage generated by the current in the varistor to the voltage generated by the current in the varistor. 3. Maximum limiting voltage: the peak voltage across the varistor under the maximum pulse peak current Ip that the varistor can withstand and under a specified waveform. 4. Residual voltage ratio: when the current through the varistor is at a certain value, the voltage generated across it is called the residual voltage for that current value. The residual voltage ratio is the ratio of residual voltage to nominal voltage. 5. Current handling capacity: current handling capacity, also known as throughput, refers to the maximum pulse current value allowed to pass through the varistor under specified conditions. 6. Leakage current: leakage current, also known as standby current, refers to the current flowing through the varistor at a specified temperature and maximum DC voltage. 7. Voltage temperature coefficient: refers to the rate of change of the varistor's nominal voltage within a specified temperature range, i.e., the relative change in voltage across the varistor when temperature changes while the current through the varistor remains constant. 8. Current temperature coefficient: refers to the relative change in current flowing through the varistor when temperature changes while the voltage across the varistor remains constant. 9. Voltage nonlinearity coefficient: refers to the ratio of static resistance to dynamic resistance of the varistor under a given applied voltage. 10. Insulation resistance: refers to the resistance value between the varistor's lead wires and the insulating surface of the resistive body. 11. Static capacitance: refers to the inherent capacitance of the varistor itself. 12. Rated power: the maximum power that causes a change in varistor voltage when operating at a specific ambient temperature. 22. Maximum surge current: the maximum surge current that causes a change in varistor voltage when the varistor is impacted by a specific pulse current once or twice.
