Description

High-low temperature heat engine test device

Technical Field

The utility model relates to a quiet rigidity test field of high low temperature environment, in particular to high low temperature heat engine test device.

Background

The lightning arrester is used for protecting electrical equipment from being damaged by high transient overvoltage during lightning stroke, limiting follow current time and normally limiting follow current amplitude. The high and low temperature rigid deformation of the high and low temperature rigid cable directly influences the lightning damage of important equipment.

The lightning arresters commonly used in the market are divided into a plurality of types, namely, a metal oxide lightning arrester, a line type metal oxide lightning arrester, a gapless line type metal oxide lightning arrester, a full-insulation composite coated metal oxide lightning arrester and a detachable lightning arrester.

The main types of arresters are tube-type arresters, valve-type arresters, zinc oxide arresters, and the like. The main operating principle of each type of arrester is different, but their operation is substantially the same, all in order to protect the communication cables and the communication equipment from damage.

The tubular arrester is a protection gap with high arc quenching capacity, and consists of two series gaps, wherein one gap is in the atmosphere and is called an outer gap, and the task of the tubular arrester is to isolate working voltage and avoid a gas production pipe from being burnt out by power frequency leakage current flowing through the pipe; the other one is arranged in the air pipe and is called an inner gap or an arc extinguishing gap, and the arc extinguishing capability of the pipe type lightning arrester is related to the size of power frequency follow current. This is a protective gap type lightning arrester, which is used for lightning protection on power supply lines in many cases.

The valve type lightning arrester consists of a spark gap and a valve plate resistor, wherein the valve plate resistor is made of special silicon carbide. The valve plate resistor made of silicon carbide can effectively prevent lightning and high voltage and protect equipment. When lightning high voltage exists, the spark gap is broken down, the resistance value of the valve plate resistor is reduced, and lightning current is led into the ground, so that cables or electrical equipment are protected from being damaged by the lightning current. Under normal conditions, the spark gap cannot be broken down, the resistance value of the valve plate resistor is high, and normal communication of a communication line cannot be influenced.

The zinc oxide lightning arrester is lightning arrester with excellent protection performance, light weight, pollution resistance and stable performance. The current flowing through the lightning arrester is extremely small (microampere or milliampere level) at normal working voltage by mainly utilizing the good nonlinear volt-ampere characteristic of zinc oxide; when overvoltage acts, the resistance drops sharply, and the energy of the overvoltage is released, so that the protection effect is achieved. The difference between the lightning arrester and the traditional lightning arrester is that the lightning arrester has no discharge gap and plays the role of current leakage and disconnection by utilizing the nonlinear characteristic of zinc oxide.

Several lightning arresters are introduced, each lightning arrester has respective advantages and characteristics, and can achieve a good lightning arresting effect only by being used for different environments.

Most of the existing high-low temperature heat engine test beds are manually operated and singly adjusted, and when the test detection is carried out by adjusting the angle of the circumferential surface, the direction needs to be manually adjusted every time, so that the data obtained by the test is unstable.
