Description

A fast access emergency power distribution system

technical field

The invention relates to an emergency power distribution system, in particular to a quick access emergency power distribution system.

Background technique

With the acceleration of my country's urban construction and the vigorous development of the electric power industry, higher requirements are put forward for the reliability of power supply, and the market demand for emergency power supply equipment is also expanding. Especially in the metropolises where the politics, economy and culture of China's provinces are relatively concentrated, the requirements for power supply reliability are higher. The investment of mobile power generation vehicles is of great significance to enhance the ability of these areas to deal with power emergencies and comprehensively improve the level of power service guarantee.

Whether it is a sudden failure in the power grid, emergency rescue and disaster relief, equipment maintenance, temporary power supply, etc., it may have a serious impact on people's production and life. Therefore, fast emergency power supply is one of the most important measures to maintain social stability and protect the most basic interests of the people, and it is also an important part of emergency rescue.

With the continuous development of the emergency power supply industry, the traditional connection methods are gradually unsuitable for various working environments, often resulting in the impossibility of emergency power supply protection work. For example, the traditional "copper nose" connection method seems simple, but in fact there are still professional requirements in terms of tool selection, force use, and tightness. In reality, the difference in professional skills of operators often leads to unreliable contact and equipment mechanical Accidents such as deformation and falling off midway. In addition, in a vibration environment, the connection method of the copper nose may become loose, and a false connection may cause dangerous problems such as heating and burning. When the traditional emergency power supply vehicle uses the "copper nose" scheme, it will inevitably encounter the following outstanding problems:

(1) If the fully enclosed low-voltage cabinet is to be connected to the cable of the generator car, the switch cabinet must be disassembled on site. This move not only increases the workload but also prolongs the rescue time. In the compact low-voltage cabinet, the internal space between phases and phases and between phases and ground is narrow, and there is no connection point for connecting the cables of the generator car. The multi-layer busbar has greatly improved the skin effect of the previous conductors and the heat dissipation of the conductors, thereby increasing the carrying capacity of the conductors. But the multilayer conductor can't solve the problem that the cable of the generator car is connected with the conventional bolt in the later stage.

(2) The body of the generator car is generally large. When the low-voltage power distribution room is in a narrow street, it is difficult for the generator car to get close to the user end. Or when the emergency power supply car is in place, it is found that the user's low-voltage power distribution cabinet is far away. Just need the cable of sufficient length at this moment, and the length of the cable that is equipped with on each generating car is limited, will appear the phenomenon that even if the generating car is driven to the scene because of cable length is not enough, can't carry out work like this. Cable extensions are therefore required in many practical situations. When using traditional copper noses for wire-to-wire connections, the speed is slow, the insulation level is low, and it is difficult to work all day The good connection of the two copper noses requires a lot of force to tighten the crimping bolts, which will also cause a lot of inconvenience during removal.

(2) It can be operated with bare hands without special tools. The new connector can be operated by any adult without any tools.

(3) The contact is more reliable. The traditional "copper nose" connection method seems simple, but in fact there are still professional requirements in terms of tool selection, force use, and tightness. In reality, it is often due to the differences in the memory of the professional skills of the operators, such as unreliable contact, mechanical failure of equipment, etc. Accidents such as deformation and falling off midway. In addition, in a vibration environment, the connection method of the copper nose may become loose, and a false connection may cause dangerous problems such as heating and burning. The new connector is easier to use, adopts international patented technology, has more reliable connection and better overload capacity.

(4) Insulation. The new connectors are insulated connectors. Has very good insulating properties. Provide absolute safety guarantee when workers operate and cable connection.

(6) It can be connected quickly. For the power supply site where the power supply distance exceeds the plan, a number of fast cables can be prepared in advance with a new type of connector. When the line is erected on site, free-hand circuit connections can be made arbitrarily. It only needs to be plugged in and completed in a few seconds, which is very convenient.

(7) Locking device. The new connector has a locking device, which can be locked by rotating 45° after insertion, effectively ensuring the safety and reliability of the connection.

(8) Prevent errors. The new type of connector has the function of error prevention, and the cable connection is more intuitive and convenient through color distinction.

(9) Long life. The new connector adopts silver-plated metal parts, and the outside is completely covered by strong insulating material, which is completely dust-proof. Compared with the traditional "copper nose", the multi-point contact core conductive terminal is used inside, which has better repeated plugging and unplugging, wear resistance and Anti-oxidation, anti-vibration, longer comprehensive life.

(10) Easy to install. The new connector is easy to modify and install, and it can be put into use immediately after simple installation on the original base station of the generator car. The user terminal has enough space to embed and install the emergency access unit and connect it to the original low-voltage power distribution device in parallel. If the space is small, only the parallel mortgage emergency access box can complete the construction transformation.

(11) Flexible application. In addition to being fixed on some equipment, the new connector can also be made into some standard line bonding devices. When there is no power distribution network outdoors, the mobile emergency power supply access box can be used to complete the rapid construction of the outdoor power distribution network. . Such as fast cables, etc., even if they are fixedly used in equipment, because of their standardized characteristics, the equipment of related equipment and tools is reduced, which greatly improves the flexibility of system equipment.

(12) Save resources. Compared with traditional solutions, the application of new connectors in the system can save manpower and material resources. Due to the characteristics of fast free-hand connection, there is no gender, strength, and skill requirements for operators, and there is no need to be equipped with tools and a large number of line erection personnel; standardization The characteristics can also be used repeatedly in different projects, reducing spare parts reserves; combined with its biggest feature of fast speed, the efficiency improvement brought by the system is the scientific optimization and improvement of resource allocation in terms of economic and social benefits.

(13) Improve power recovery efficiency. Fast on-site connection and all-weather working environment can effectively improve the efficiency of power recovery and reduce the rate of user complaints.
