Product Description
Product Description
Environmental Test Equipment High and Low Temperature Test Chamber
Partial discharge detector is suitable for the online partial discharge measurementof electrical apparatus, such as surge arresters, insulators, power transformers,generators, CT/VT, GIS, capacitors, power cables and switchgears.
Used in conjunction with the partial discharge detection system, it simulates both high and low temperatures as well as high and low pressures to create favorable testing conditions.
technical specification | |
*1 | Voltage: 0~5000VAC (adjustable, settable value input, AC frequency: 50~800Hz, frequency adjustable); |
*2 | Altitude: 0~30000 meters (1.06kpa~100kPa, adjustable, settable value input); |
*3 | Temperature range: -55℃~180℃ (adjustable, settable value input); |
*4 | Partial discharge sensitivity meets the test requirement of ≤0.1pC, and at the same time, the partial discharge quantity of 3pC will generate a readable value higher than the background noise on the discharge meter or oscilloscope; |
Parameters of Temperature-Humidity-Altitude Chamber | |
*5 | Humidity meets two gears: ≤30% and 98% (humidity is displayable, temperature is adjustable within the range of 20~80℃), referring to GJB150-19. |
*6 | Volume of heat preservation and pressure maintaining chamber: 1.6m×1m×0.8m (internal dimensions can be slightly larger than this size, but not smaller). |
7 | Air pressure resolution: 0.01kPa. |
*8 | Air pressure deviation: ≤±5% (1kPa~2kPa); ≤±0.1kPa (2kPa~4kPa); ≤±0.2kPa (4kPa~40kPa); ≤±2kPa (>40kPa). Temperature deviation: ≤±2.0℃, Humidity deviation: +2/-3% (>75%RH), ±5% (≤75%RH) |
9 | The equipment requires an observation window, with anti-condensation, defrosting, and lighting requirements. |
10 | The compressor should have temperature, pressure and other protection measures to prevent compressor damage. The compressor's inlet and exhaust should have pressure display, and pressure and temperature sensors should be installed at the exhaust and suction ends of the compressor, which can monitor and control the real-time dynamic pressure during the operation of the compressor, so that the compressor always operates under normal working conditions; the compressor should be selected from Copeland . |
*11 | Equipment data collection requirements: The equipment supports network communication with RJ45 standard network port. It supports setting IP, gateway, and subnet mask. The MAC address is readable. The equipment needs to support Modbus (TCP/RTU) communication protocol and provide point table and command examples. |
*12 | After-sales service: 1. Provide cooperative assistance for data collection; 2. If there is any abnormality in the equipment instrument interface communication, solve the communication problem. |
Specification
Applications
Performance verification: Testing whether the product functions normally under high temperatures (e.g., +150°C) and low temperatures (e.g., -70°C) (such as the operation of electronic components and the deformation of plastic parts);
Aging/life assessment: Accelerating the aging process of products in temperature-varying environments to predict their actual service life in practical use;
Material compatibility testing: Verifying changes in the physical/chemical properties of materials (such as rubber and metal) under high and low temperatures (such as embrittlement and expansion);
Quality screening: Exposing product design or process defects in advance to prevent unqualified products from entering the market.

Key Configurations
Temperature Control Preparation Module
Refrigeration system: Commonly uses "compressor + refrigerant" (such as R404A); high-end models may be equipped with two-stage compression to achieve ultra-low temperatures.
Heating system: Mostly stainless steel heating tubes/nichrome heating wires to ensure that express packages in the chamber are heated.
Test Chamber
Inner container: Corrosion-resistant stainless steel (such as 304/316) to ensure cleanliness and durability.
Insulation layer: Polyurethane foam + rock wool to reduce temperature loss inside the chamber.
Chamber door: Equipped with an observation window (tempered glass) + sealing strip, taking into account visualization and sealing performance.
Control System
Controller: Mainstream uses PLC or touch screen (such as PID intelligent regulation), supporting temperature change program setting.
Sensor: Temperature probe (such as PT100) to monitor the temperature inside the chamber in real time.
Auxiliary Function Configuration
Safety protection: Over-temperature alarm, compressor overload protection, leakage protection.
Optional functions: Humidity control (upgraded to a high and low temperature test chamber), temperature change rate adjustment (rapid temperature change type), sample racks/test interfaces, etc.
