The fully automatic temperature rise test device under Wuhan UHV can help many power workers conduct various power tests more conveniently.
The core technical parameters and performance levels are the basis for price stratification of Wuhan UHV and high voltage temperature rise test bench. For the testing of 110kV-220kV medium and high voltage equipment, the Wuhan UHV-WS300 series test bench has an output current range of 0-5000A and adopts a dry air cooling design. The current waveform distortion is less than 1%, and the temperature measurement accuracy is ± 0.5 ℃, which can meet the temperature rise testing requirements of conventional equipment such as switchgear and circuit breakers. The basic performance configuration makes its price more suitable for general testing scenarios; For ultra-high voltage equipment of 330kV and above (such as GIS and transformer bushings), the UHV-WS500 series test bench increases the output current to 0-10000A, equipped with imported high permeability current collectors and 64 channel temperature inspection instruments, supports 24-hour continuous operation, and meets the strict standard of DL/T 1572. The increase in core component cost and technical complexity is directly reflected in the price difference; For the testing of high-voltage energy storage equipment in the field of new energy, customized test benches are equipped with DC output modules (0-8000A) and ripple suppression functions to meet the special requirements of DC high-voltage scenarios. The cost of customized technology research and development will be included in the pricing system.
The richness of functional configuration directly affects the price positioning of Wuhan UHV and high voltage temperature rise test bench. The basic test bench only has current regulation, temperature acquisition, and data display functions, suitable for simple temperature rise verification scenarios, and the price is relatively affordable; Enhanced models (such as UHV-WS300B) have added data storage (supporting 100000 records), USB export, and sound and light alarm functions. Equipped with Siemens S7-30 PLC control system, the automation level of operations has been significantly improved, and the addition of functional modules has led to price increases; The intelligent version (such as UHV-WS500A) is equipped with a 15 inch touch industrial tablet, supporting fully automatic operation of the test process, real-time generation and remote monitoring of temperature rise curves, and built-in GB and IEC standard test templates. The software development and hardware upgrade costs are higher, and the price is correspondingly higher than the basic and enhanced versions. In addition, the availability of standard calibration certificates and third-party testing reports may also affect the final price due to differences in certification costs.
The demand for scenario based customization is a key variable that leads to price differences in the Wuhan UHV and high voltage temperature rise test bench. For the on-site inspection needs of outdoor substations, customized designs must adopt IP44 protection level design, equipped with large capacity mobile power supplies and portable cabinets. The cost of structural renovation and protective materials will be reflected in the price; For the long-term testing needs of ultra-high voltage equipment, customized models can be equipped with efficient water cooling systems, supporting continuous operation of rated current for more than 8 hours. Upgrading the cooling module will increase the price; For overseas projects, customized products must comply with CE certification standards, be compatible with multilingual operating interfaces and different voltage standards (such as 110V/60Hz), and certification testing and software localization costs become an important part of the price composition. In addition, special fixtures customized according to customer needs (such as irregular busbar testing fixtures) may also incur additional price adjustments due to high processing accuracy and material requirements.
Supporting equipment and compatibility are important factors in considering the price of Wuhan UHV and high voltage temperature rise test bench. A simple set that only includes the host and basic wires, with a relatively low price; The complete configuration plan includes a high-precision voltage divider, Roche coil, temperature probe (standard 60 pieces), and portable storage box. All auxiliary equipment has undergone compatibility testing to ensure signal delay error ≤ 0.5 μ s. The procurement and integration costs of supporting equipment will be reflected in the price; For the existing detection system of the customer, Wuhan UHV can provide interface adaptation services, connect the test bench with the existing data management platform, and the technical debugging cost required for adaptation and transformation will be included in the overall quotation. For bulk purchasing customers, installing linkage control modules for multiple devices may increase costs, but it can significantly improve detection efficiency and have long-term economic benefits.
The after-sales service and technical support content indirectly affect the price of the Wuhan UHV and high voltage temperature rise test bench. A service package that only provides a one-year basic warranty and instruction manual guidance, corresponding to lower equipment prices; The value-added package includes "2-hour response+48 hour on-site service" and free calibration once a year. Due to the investment of professional engineer labor costs, the price is higher than the basic service plan; We provide a 3-year warranty for the entire machine, a 5-year warranty for core components (such as the current regulator and temperature measurement module), and lifetime technical support. The maintenance and guarantee costs are higher in the later stage, and the corresponding equipment prices are more cost-effective. In addition, value-added services such as on-site installation and debugging, operation training (including parameter settings and troubleshooting) after equipment delivery, if included in the overall plan, will also be reasonably reflected in the price composition.
In summary, the price of Wuhan UHV and high voltage temperature rise test bench has formed a differentiated system around "performance configuration service", which not only avoids "cost waste caused by functional redundancy", but also eliminates "insufficient configuration affecting testing needs". Customers need to clarify the testing objects (medium high voltage/ultra-high voltage), scene characteristics (laboratory/site), functional requirements (basic/intelligent), and service expectations. Wuhan ultra-high voltage will provide matching solutions and price suggestions based on this information to ensure accurate equivalence between price and usage value.
