05/8/1 electrical components are commonly used low-current master control devices. They utilize the collision of moving parts of production machinery to actuate their contacts, thereby connecting or disconnecting control circuits to achieve specific control objectives. Typically, such switches are used to limit the position or travel of mechanical motion, causing the moving machinery to automatically stop, reverse, change speed, or perform automatic reciprocating motion at a specified position or travel. In electrical control systems, the role of position switches is to implement sequence control, positioning control, and detection of position status. They are used to control the travel of mechanical equipment and provide limit protection. Structure: Composed of an operating head, contact system, and housing. In actual production, limit switches are installed at predetermined positions. When a module mounted on the moving parts of the production machinery strikes the limit switch, the contacts of the limit switch actuate, achieving circuit switching. Therefore, a limit switch is an electrical device that switches circuits based on the travel position of moving parts; its operating principle is similar to that of a pushbutton. Limit switches are widely used in various machine tools and lifting machinery to control their travel and provide terminal limit protection. In elevator control circuits, limit switches are also used to control the speed of opening and closing car doors, automatic door opening/closing limits, and upper/lower limit protection for the car.

05/8/1 Electrical Component Composition

1. The wiring harness is designed to facilitate installation and maintenance, ensuring that electrical equipment can operate under the most severe conditions. It integrates wires of different specifications and colors used by various electrical devices in the vehicle through reasonable arrangement, bundling them together with insulating materials to ensure completeness and reliability. 2. Proper selection of wire cross-sectional area and color codes: ① Correct selection of wire cross-sectional area: Electrical equipment on the vehicle selects the wire cross-sectional area based on the magnitude of the load current. For electrical equipment operating for extended periods, 60% of the actual current-carrying capacity of the wire may be selected; for short-term operation, 60%-107% of the actual current-carrying capacity may be used. ② Selection of wire color codes: To facilitate identification and maintenance, wires in the harness are differentiated by color. For ease of annotation in circuit diagrams, wire colors are represented by letters, with corresponding color explanations provided in each wiring diagram.

05/8/1 Electrical Component Classification

Thermosensitive materials are generally classified into three categories: semiconductor, metal, and alloy types: 1. Semiconductor thermistor materials include single-crystal semiconductors, polycrystalline semiconductors, glass semiconductors, organic semiconductors, and metal oxides. They all possess very large temperature coefficients of resistance and high resistivity, resulting in sensors made from them having relatively high sensitivity. Based on the temperature coefficient of resistance, they can also be divided into negative temperature coefficient (NTC) materials and positive temperature coefficient (PTC) materials. For example, barium titanate ceramic is an ideal semiconductor material with a positive temperature coefficient of resistance. Both types of materials are widely used in temperature measurement, temperature control, temperature compensation, switching circuits, overload protection, and time delay applications, such as in the manufacture of thermistor thermometers, thermistor switches, and thermistor delay relays. Due to the exponential relationship between resistance and temperature, the temperature measurement range is narrow and uniformity is poor. 2. Metal thermistor materials are widely used as thermal resistors for temperature measurement, current limiters, and automatic constant-temperature heating elements, such as platinum resistance thermometers, nickel resistance thermometers, and copper resistance thermometers. Among these, platinum temperature sensors exhibit significantly high precision and stability in various media (including corrosive media). However, their widespread application is somewhat limited due to the scarcity and high cost of platinum. Copper temperature sensors are less expensive, but long-term use in corrosive media can lead to significant changes in static characteristics and resistance values. Nickel temperature sensors are widely used abroad and are considered a relatively ideal material because they offer high sensitivity, satisfactory reproducibility, and stability. 3. Alloy thermistor materials, also known as thermistor alloys. This type of alloy has relatively high resistivity, and its resistance value is sensitive to temperature changes, making it a good material for manufacturing temperature-sensitive sensors. The performance requirements for thermistor alloys used as temperature-sensitive sensors are as follows: (1) sufficiently high resistivity; (2) relatively high temperature coefficient of resistance; (3) linear expansion coefficient close to that of the experimental material; (4) low strain sensitivity coefficient; (14) good repeatability of the resistance-temperature curve during heating and cooling within the operating temperature range.

05/8/1 Electrical Component Characteristics

Common types include RC phase-shifting bridge trigger circuits, unijunction transistor trigger circuits, bipolar junction transistor trigger circuits, and trigger circuits using small thyristors to trigger large thyristors, etc. The main parameters of thyristors are: 1, rated on-state average current IT: the average value of the 50 Hz sinusoidal half-wave current that can continuously pass between the anode and cathode under specified conditions. 2, forward blocking peak voltage VPF: the repetitive forward peak voltage that can be applied across the thyristor when the gate is open without a trigger signal and the forward anode voltage has not exceeded the turn-on voltage. The forward peak voltage withstandable by the thyristor must not exceed this parameter value given in the manual. 3, reverse blocking peak voltage VPR: the repetitive reverse peak voltage that can be applied across the thyristor when reverse voltage is applied and the thyristor is in the reverse blocking state. During use, this parameter value given in the manual must not be exceeded. 4, trigger voltage VGT: the minimum gate current and voltage required to switch the thyristor from the off state to the on state when a certain voltage is applied between the anode and cathode at a specified ambient temperature. 8, holding current IH: the minimum anode forward current required to maintain the thyristor in the conducting state at a specified temperature with the gate circuit open. Many new types of thyristor components have been introduced, such as fast thyristors suitable for high-frequency applications, bidirectional thyristors that can conduct in both directions controlled by positive or negative trigger signals, and thyristors that can be turned on by a positive trigger signal and turned off by a negative trigger signal.
