Description

Technical Field

[0001] The utility model relates to the technical field of transformer substation equipment, in particular to a box-type isolation transformer substation. Background Art

[0002] The so-called substation is a device used to change voltage. In order to transmit the electric energy generated by the power plant to a distant place, the voltage must be increased and converted into high voltage electricity. When it reaches the user's vicinity, the voltage must be lowered as needed. This work of raising and lowering voltage is completed by the substation. The main equipment of the substation is switches and transformers. According to different sizes, it is called a substation, substation, distribution room, etc.

[0003] There are currently two types of box-type substations supporting power plants. One is the combined box-type substation, that is, the American box-type substation, and the other is the European box-type substation. However, the existing European box-type substations are similar to conventional box-type substations in appearance, structure and layout, including the transformers, and have the same basic functions. They all use 40.5kV intelligent pre-installed box-type substations for wind power generation, and complete the conversion of wind power from low voltage to high voltage through the boost system, and finally merge into the power grid. However, the high-voltage installation area and the low-voltage installation area inside the current substation are relatively close, and the heat dissipation performance of the two is poor during actual work. At the same time, due to the large number of electrical components distributed, the internal wiring is complicated. When the staff conducts maintenance and management of the substation in the later stage, it is not conducive to sorting out the electrical component lines inside the substation.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] See also Figure 1-3 The present embodiment provides a box-type isolated substation, comprising a mounting bracket 1, an isolation mounting plate 2, a high-voltage mounting area 3, a low-voltage mounting area 5 and a transformer assembly 6. An isolation top plate 4 is arranged above the mounting bracket 1, and a high-voltage mounting area 3 and a low-voltage mounting area 5 are arranged on the mounting bracket 1.

The transformer assembly 6 is arranged on the heat-insulating mounting bottom plate 7, and an isolation mounting plate 2 is arranged at the rear side of the transformer assembly 6, and the low-voltage mounting area 5 is arranged at the rear side of the isolation mounting plate 2.

[0020] Furthermore, a high-voltage installation area isolation plate 301 and an electrical component mounting rack 302 are provided in the high-voltage installation area 3. The high-voltage installation area isolation plate 301 is provided in the middle position between the high-voltage installation area 3 and the transformer assembly 6. The electrical component mounting rack 302 is provided at the edge position of the high-voltage installation area isolation plate 301. The electrical component mounting rack 302 is provided with a plurality of evenly distributed mounting slots.

[0021] Furthermore, the low-voltage installation area 5 includes a low-voltage wiring slot 501, a voltmeter 502, a capacitor 503 and a compensation controller 504. The low-voltage wiring slot 501 is set at the lowest side of the low-voltage installation area 5, and the voltmeter 502 is set above the low-voltage wiring slot 501. The capacitor 503 is set above the voltmeter 502, and the compensation controller 504 is set above the capacitor 503. The compensation controller 504 controls the capacitor 503. When the detected voltage is greater than the set overvoltage protection threshold, all the capacitors 503 that have been put into use are cut off in groups; when the detected voltage exceeds 10% of the set overvoltage protection threshold, all the capacitors 503 that have been put into use are cut off at one time, thereby protecting the electrical components set on the low-voltage installation area to work normally. The compensation controller 504 is provided with an RS485 communication interface, which can transmit the voltage, current, temperature and other parameters transmitted inside the low-voltage installation area to other devices through the communication interface, so as to facilitate the subsequent staff to test and inspect the electrical components inside the substation.

The slide rail 203 provided on the movable mounting bracket 202 allows the wire combing strip 204 to move thereon, and adjust the wire position according to the actual installation position of the electrical components, thereby facilitating the wire combing work inside the substation. At the same time, a self-locking buckle 205 is provided below the isolation mounting plate 2, which can improve the degree of fixation between the isolation mounting plate 2 and the mounting bracket 1.

[0023] Furthermore, drainage grooves 401 are provided on both sides of the isolation top plate 4, and grooves are provided on the drainage grooves 401. The isolation top plate 4 has good drainage performance, and when too much rainwater accumulates above, it can be discharged through the drainage grooves 401, thereby avoiding the situation where excessive pressure above the substation occurs due to excessive rainwater.
