uniross electrical components refer to the aggregate of service equipment provided for a specific group of load sources, such as trunk lines, switching devices, and control systems. The fundamental research content of traffic theory is to study the relationship between traffic volume, call loss, and bundle capacity; therefore, the line bundle is an important basic concept in traffic theory. The load source is the service object of the line bundle, usually referring to user equipment; broadly speaking, the upper-level equipment is the load source for the lower-level equipment. In telephone communication, the load source is also called the traffic source. The number of service devices contained in the line bundle is called the bundle capacity. Figure 1 is a schematic diagram of the line bundle. The capacity of this line bundle is V, and it provides service for N load sources. Any load source initiating a call can occupy an idle service device in the line bundle.

uniross electrical component characteristics

Under normal circumstances, the actual static characteristic output of a sensor is a curve rather than a straight line. In practical work, to enable instruments to have uniformly scaled readings, a fitted straight line is often used to approximately represent the actual characteristic curve. Linearity (non-linear error) is a performance indicator of this degree of approximation. There are various methods for selecting the fitted straight line. For example, the theoretical straight line connecting the zero input and full-scale output points is used as the fitted straight line; or the theoretical straight line with the minimum sum of squared deviations from each point on the characteristic curve is used as the fitted straight line, which is called the least squares fitted straight line.

uniross electrical component function

The starter solenoid switch is a key component of the starter, and the design quality of the solenoid switch directly affects the reliability of the starter. The starter solenoid switch has two functions: one is to connect the main circuit to make the starter rotate, and the other is to push out the drive gear through the shift fork to engage with the engine flywheel ring gear. Therefore, the solenoid switch is required to have corresponding suction force, corresponding stroke, and contacts that can reliably connect and disconnect high current. In addition, it is required to minimize volume and weight as much as possible. Based on the above characteristics, the contact structure of the solenoid switch generally adopts a contact form, that is, the moving contact is made into a bridge piece or disc shape to provide a larger heat dissipation surface and heat capacity. The magnetic system mostly adopts a solenoid electromagnet structure to meet the requirements of corresponding stroke, corresponding suction force, small volume, and light weight. The moving iron core of the solenoid switch can move smoothly in the brass bushing equipped with a solenoid coil. The moving iron core pull rod is connected to the shift fork unidirectional device. Under the action of the return spring, the moving iron core normally remains in the initial non-working position. During starting, the starter drive gear needs to move forward by about 12-29mm. Therefore, when the solenoid switch begins to close, a large magnetomotive force is required to generate the necessary initial suction force. After being pulled in, the air gap decreases, and the electromagnetic suction force increases sharply, greatly exceeding the force required to maintain the closed state. For this reason, the solenoid switch adopts two coils (pull-in coil and holding coil). At the beginning, the pull-in coil and holding coil jointly generate electromagnetic suction force. After the switch contacts are closed, the pull-in coil automatically disengages from the working state, and the holding coil alone maintains the switch in the closed state. The holding coil current is relatively small and can be wound with thinner wire, which not only reduces the volume of the solenoid switch but also achieves reasonable suction force matching. To ensure the reliability of the starter, it is necessary to focus on controlling the design quality of the solenoid switch.

A thermopile is a pyroelectric infrared sensor, which is a device composed of thermocouples. It has been widely used as a temperature detection device in fields such as ear thermometers, radiation thermometers, electric ovens, and food temperature detection. It is composed of two or more thermocouples connected in series, and the thermoelectric potentials output by each thermocouple are superimposed on each other. Used to measure small temperature differences or average temperatures. Structure of the thermopile: The radiation receiving surface is divided into several blocks, each connected to a thermocouple. Connecting them in series forms a thermopile. Depending on the application, practical thermopiles can be made into filament type and thin film type, and can also be made into multi-channel and array devices.
