Description
Technical Field
The utility model relates to a transformer substation protection measurement and control device technical field, concretely relates to box-type substation protection measurement and control device of integrated automatic fire control function.
Background
The box-type transformer substation is a commonly used outdoor power transformation complete device in various industries, particularly the application of the new energy industry, the power generation unit of each new energy station adopts the box-type transformer substation for boosting, and the oil-immersed transformer is a conventional transformer configuration type. Because the oil injection type box transformer substation is likely to cause explosion after open fire is generated due to internal or external faults, the personal safety of nearby personnel and the safety of the surrounding ecological environment and property can be seriously threatened.
According to national safety regulations, the main technical route for fire protection of the box-type substation is passive fire protection, i.e. fire accidents are prevented from spreading mainly by the fire-resistant and flame-retardant properties of the box material. The fire protection of the box of a box-type substation usually uses steel, aluminium alloy plates and is filled with glass fibre, asbestos or synthetic materials with fire resistance. According to the national standard "high-low voltage pre-installed substation" (GBT 17467-2020), the fire protection performance of a box substation is only required in consideration of the box housing material, i.e. the minimum performance level on fire inside or outside and the non-flammability requirements of the relevant materials. Meanwhile, various regulations and typical designs at the present stage do not consider or suggest an active fire-fighting scheme.
The existing passive fire prevention mode has low timeliness for treating accidents: the box-type substation and the single power generation unit are distributed after being combined. In a single wind power plant, the space span of the arrangement of the wind driven generator and the box-type substation in the field area is large and can reach dozens of kilometers. Booster stations which are constructed in a matching way in a wind power plant are mostly arranged nearby in a region, but a wider space span and the height fluctuation of the terrain are determined, and roads in the wind power plant for accident reaction are possibly longer, difficult to pass and complicated. This also causes the operation and maintenance personnel who are stationed in the booster station to arrive at the site for tens of minutes or even more than one hour after the fire accident of the box-type substation occurs. Therefore, in some specific cases, after a fire accident occurs in the box-type substation of the wind power plant, it is difficult for field operation and maintenance personnel or fire departments to arrive at the field in a short time for processing and extinguishing the fire accident. At present, the passive fire prevention mode of the box-type substation is difficult to guarantee the timeliness of fire prevention and fire fighting under the application scene of a new energy power station.
The possible accident of the existing passive fire prevention mode is enlarged if a fire disaster happens: in the new energy industry, particularly wind power plants, sites are generally selected in areas with rare people or areas with important ecology. For example, in northern west and other regions, wind farms are in grasslands, and in autumn and winter, due to dry climate, grassland fire is easily caused by a fire accident of box-to-box transformation. If the timeliness and reliability of the passive fire prevention mode cannot be guaranteed, the accident is easy to expand.
From the above, it is urgently needed to solve the above problems by the technical solution of the present application.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the not enough of above-mentioned prior art, provide the conflagration hidden danger in the automated inspection transformer substation, in time carry out conflagration work of putting out, can avoid the box-type substation protection measurement and control device of an integrated automatic fire control function that the fire incident enlarges.
