Intelligent pre-assembled box-type substation

This type of product is a combination of high-voltage electrical equipment, transformer, low-voltage electrical equipment, etc. into a compact complete set of devices for urban high-rise buildings, urban and rural buildings, residential neighborhoods, high-tech development zones, small and medium-sized factories, mines and oilfields as well as temporary construction of electric places, as the power distribution system to receive and distribute power. The box variable adopts 3 invention patents and 5 utility model patents of our company, with micro-sensor, weak-signal power supply microcomputer protector (Patent No.: 201120035866.8), high-voltage energy meter metering (Patent No.: 200710014037.X), which can be used to measure the error directly. Compared with the current box-variable products, the protection action is more sensitive, the measurement accuracy is higher, anti-electricity theft, the chance of failure is very small, energy saving and material saving, remote meter reading, wireless display of data and record the power changes at any time, realizing the integration and intelligentization.

Model Meaning

Product Characteristics

Intelligent integrated substation (invention patent No.: 201110036645.7) is a new type of substation designed by integrating a number of patented products with independent intellectual property rights of our enterprise.

High-voltage metering by sensor-type high-voltage energy meter

The high-voltage side adopts our company's patented product (Patent No.: 200720019883.6) - sensor-type high-voltage energy meter, which is safe and reliable, reduces the chance of grid failure, prevents power theft, saves energy and materials, is easy to install and use, and measures accurately and with a uniquely determined error, and so on.

The use of sensors and weak signal microcomputer protector to form a microcomputer protection system

The microcomputer protection system has self-diagnostic function for both hardware and software, and will issue a warning once an abnormality is found, thus greatly reducing the workload of operation and maintenance.

GPRS, optical fiber, carrier wave and other transmission, to realize the remote function products can be RS485, GPRS, optical fiber, carrier wave and other ways to transmit data back to the display unit, and can realize the remote function.

Adoption of delta three-dimensional energy-saving transformer

Transformer using energy-saving S11 (S13) delta-dimensional oil-immersed power transformers and energy-saving delta-dimensional dry-type transformers. The material is not less than 30ZH110 cold rolled silicon steel sheet; three-phase three-column three-dimensional symmetrical structure has the most balanced three-phase magnetic circuit; each group of heart piece by thin steel belt in the special core winding machine winding and become, the pressure is even and tight. The use of triangular structure of the fully sealed corrugated oil tank, three-phase are set up corrugated sheet to ensure heat dissipation and compensate for changes in oil temperature with the oil volume caused by changes in the volume of oil expansion volume; box cover is equipped with a pressure relief valve oil level meter to facilitate refueling and observation of the oil level height, and the transformer inside the sudden break fault overvoltage pressure release, safety protection.

The use of temperature, gas and other sensors, to achieve the fault warning function

Products using temperature, gas and other sensors, with protection functions can be issued before the occurrence of failure alarm, to avoid accidents, greatly improving the safety performance of the product.

Energy saving effect is obvious

The direct energy saving of this series of products should be equal to the energy saving of the metering unit plus the energy saving of the energy-saving transformer. The energy-saving effect of transformers of different capacities varies with 500kVA, for example, the calculation, each unit can save 21,000 kilowatt-hours of electricity per year (equivalent to 8 tons of standard coal); saving electricity costs 13,100 yuan.

Higher safety performance, longer service life

In-line fuse: prevent the expansion of the fault, only close to the fault point of the fuse action, does not affect the superior fuse, and molded case switch in the event of a fault, the emergence of cross-stage circuit breaker tripping; small size, each cabinet can be installed multiple outlets, long service life and does not affect the protection characteristics; and reduces the primary current power saving, improve safety performance.

With interlocking function and reasonable structural design

High and low voltage room layout is reasonable and compact, easy to operate and maintain, high-voltage switchgear with anti-misoperation chain function; transformer can be easily accessed from the track to the transformer room door according to the user's requirements; each room is equipped with automatic lighting device, in addition to the high and low switchgear selected components are reliable, easy to operate, easy to maintain. The top cover of the transformer is double-layer heat-insulating structure to reduce the sunlight radiation effect, and the base is section steel structure with sufficient strength and rigidity. Transformer top is non-metallic structure double layer, inside the heat insulation layer and ventilation channel with automatic exhaust ventilation device, there is a temperature control instrument, to ensure that the full load running temperature will not be too high.
