Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments.

[0037] In the following description, the terms "first\second" are only to distinguish similar objects, and do not represent a specific order of the objects. Understandably, "first\second" can be interchanged in a specific order or sequence as allowed, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0039] A valve hall equipment arrangement and a construction method thereof are provided.

[0040] As shown in Figure 1 and Figure 2 , the present application provides a valve hall equipment arrangement, comprising: a first layer and a second layer arranged in a vertical direction from bottom to top; wherein,

[0041] As shown in Figure 1 , the first layer is used to arrange a plurality of floor-mounted converter valve towers 1;

[0042] As shown in Figure 2 , the second layer is located above the first layer and is separated from the first layer by a floor slab, and is used to arrange bridge arm reactors 2 and starting circuit equipment 3;

[0043] The converter valve towers 1 are electrically connected to the bridge arm reactors 2 and the starting circuit equipment 3, respectively.

[0044] In the present application, the first layer is the main equipment area of the valve hall, and the ground is an anti-static epoxy floor. A plurality of converter valve towers 1 are directly installed on the ground and are arranged in two rows in symmetry, with a wide main operation and maintenance passage reserved in the middle. Each converter valve tower 1 can be stacked by a plurality of power sub-modules and is the core power unit for realizing AC / DC conversion. The second layer is located above the first layer and is physically separated from the first layer by a solid floor slab. In the present application, the floor slab uses a steel truss as the main load-bearing framework, and high-strength concrete is poured on it to form a concrete slab. This structure ensures that it has sufficient mechanical strength to bear the heavy equipment on the upper layer. The second layer space is further divided into a reactor area and a starting circuit area according to the function. In the reactor area, a plurality of bridge arm reactors 2 are arranged in a straight line, and each bridge arm reactor 2 is fixed to the floor slab by a support, and its position corresponds to the vertical projection of the converter valve tower 1 in the lower layer. Among them, Figure 1 A, B, and C represent different equipment.

[0045] In the starting circuit area, a plurality of starting circuit equipment 3 can be arranged. For example, starting resistors, associated disconnectors, arresters, and voltage transformers, etc.

[0046] The application significantly improves the space utilization and saves the precious land resources without increasing the floor area of the valve hall, and is especially suitable for the power site with land shortage. The physical separation of the core power unit and the auxiliary control / protection unit is realized, and the device operation environment is improved. The vibration of the upper reactor and the heat dissipation of the starting resistor are minimized to the lower precision converter valve tower 1, and the system reliability is improved.

[0047] In some embodiments, the floor is embedded with cooling pipes connected to the cooling system of the valve hall, forming an auxiliary cooling circuit for the first layer converter valve tower 1.

[0048] The cooling system provided in the application cools the first layer converter valve tower 1 by the main water cooling system (not shown in the figure) through the trench or the bottom pipe. In addition, the cooling pipes are embedded in the concrete floor of the second layer, which are connected to the auxiliary cooling system of the valve hall and can be used as a supplementary heat dissipation means for the first layer converter valve tower, effectively removing the hot air rising from the lower layer.

[0049] In some embodiments, as shown in Figure 3 Further comprising: an electrical connection bus 4;

[0050] The electrical connection bus 4 passes through the floor of the second layer, and is used for electrical connection between the first layer converter valve tower 1 and the second layer bridge arm reactor 2 or starting circuit device 3.

[0051] In some embodiments, the floor is provided with a through-penetration device for the electrical connection bus to pass through, and the through-penetration device is filled with electromagnetic shielding material and outer sealing structure.

[0052] In order to realize the electrical function, the converter valve tower 1 is connected to the second layer bridge arm reactor 2 and starting circuit device 3 through the electrical connection bus 4 between the layers. The electrical connection bus 4 can pass through the load-bearing floor of the second layer vertically. At the floor-penetrating position, a special through-penetration device is arranged. The through-penetration device is filled with metal waveguide or wave-absorbing material, and the outside is sealed by a rubber ring, so as to realize the electrical connection while ensuring the electromagnetic shielding efficiency and environmental cleanliness of the valve hall as a whole.

[0053] In some embodiments, the space of the second layer is divided into a reactor area and a starting circuit area according to the device function, and a fireproof partition or wall is arranged between the reactor area and the starting circuit area.

[0054] In some embodiments, the second layer is also provided with an operation and maintenance channel and a lifting facility, which are used for installation, maintenance and replacement of the equipment of the second layer without affecting the operation of the converter valve tower 1 of the first layer.

[0055] The lifting facility is a light bridge crane.

[0056] The track of the light bridge crane is laid on the corbel bracket pre-set on the side wall of the second layer, and the maximum lifting height of the crane is adapted to the headroom height of the second layer.

[0057] In the present application, the side wall of the second layer is provided with a corbel bracket, and a light bridge crane is installed on the corbel bracket. The lifting range of the light bridge crane can cover all the upper layer equipment, facilitating installation and maintenance. The maintenance work of the upper layer equipment can be carried out through the crane, completely without affecting the normal operation of the lower layer converter valve tower. The main operation and maintenance channel of the first layer and the staircase / platform of the second layer jointly constitute a three-dimensional operation and maintenance channel system.

[0058] In the present application, the bridge reactor 2 and the starting circuit and other large auxiliary equipment are "stacked" on the core converter valve tower. Without increasing the floor area of the valve hall, the space utilization is significantly improved, and the valuable land resources are saved, which is especially suitable for power sites with land shortage. The physical separation of the core power unit and the auxiliary control / protection unit is realized, and the equipment operation environment is improved. The vibration of the upper layer reactor and the heat dissipation of the starting resistor are minimized to the lower layer precision converter valve tower, and the system reliability is improved.

[0059] In addition, in the present application, the solid concrete floor and the shielding penetrator jointly constitute an effective electromagnetic isolation layer, reducing the mutual electromagnetic interference between the upper and lower layer equipment. The three-dimensional layered structure makes the equipment layout well-ordered, and the maintenance or replacement of the equipment of a layer can be carried out without affecting the equipment of another layer, improving the safety and efficiency of the operation and maintenance work.
