Switching cabinet - switch cabinet delivery operation program
Power supply operation
First pack the back plate and close the front and the lower door
Operate the spindle of the grounding switch and make it cut
To push the handcart (in the sluice state) into the cabinet (the test position) with a transporter (a platform car).
Put two plugs on the plug
(test position indicator light)
(shut the door before)
Push the handcart from the test position (sluice state) into the working position with the handle
(work position indicator is bright, test position indicator is extinguishing)
Closing circuit breaker handcart
Power outage (maintenance) operation
Switch the switch of a circuit breaker
Pull the handcart from the working position (sluice state) to the test position with the handle
(work position indicator is extinguished, test position indicator is bright)
Open the front door
Pull two plugs out of the plug
(test position indicator extinguish)
Out of the cabinet by a transshipment vehicle (in the state of the sluice)
Operating the spindle of the grounding switch and closing it
Open the back plate and the front and lower doors
Note: the lower lightning arrester and the middle (lower) PT handcart can be pulled out of the cabinet directly when the bus is running.

What is the difference between the Guizhou switchgear - the distribution box and the switchgear
Generally speaking, the box that distributes electric energy is called a distribution box. It is mainly used as the control and distribution of electric equipment, and it protects the overload, short circuit and leakage of the line. The distribution box is installed in various places, such as schools, organs, hospitals, factories, workshops, families and so on, such as lighting distribution boxes, power distribution boxes and so on.
A switchgear is a complete set of switchgear and control equipment. It is used as a power center and a main distribution device. It is mainly used for control, monitoring, measurement and protection of electric power lines and main electrical equipment. It is often set up in substations, distribution rooms and so on.
Distribution box and switch function, in addition to the installation environment, internal structure, controlled object different, notable feature is the size, distribution box has the advantages of small size, can be set in the dark wall, can stand on the ground; and the volume of the switch cabinet, only device in transformer substation, power distribution room.
开关柜（switch cabinet）是一种电气设备，开关柜外线先进入柜内主控开关，然后进入分控开关，各分路按其需要设置。如仪表，自控，电动机磁力开关，各种交流接触器等，有的还设高压室与低压室开关柜，设有高压母线，如发电厂等，有的还设有为保主要设备的低周减载。 开关柜（switchgear）的主要作用是在电力系统进行发电、输电、配电和电能转换的过程中，进行开合、控制和保护用电设备。开关柜内的部件主要有断路器、隔离开关、负荷开关、操作机构、互感器以及各种保护装置等组成。开关柜的分类方法很多，如通过断路器安装方式可以分为移开式开关柜和固定式开关柜；或按照柜体结构的不同，可分为敞开式开关柜、金属封闭开关柜、和金属封闭铠装式开关柜；根据电压等级不同又可分为高压开关柜，中压开关柜和低压开关柜等。主要适用于发电厂、变电站、石油化工、冶金轧钢、轻工纺织、厂矿企业和住宅小区、高层建筑等各种不同场合。
The switchgear (switch cabinet) is an electrical device. The outside of the switch cabinet is advanced into the main switch of the cabinet, then it enters the sub control switch, and the branches are set according to their needs. For example, instruments, automatic control, motor magnetic switches, various AC contactors, etc., some of them also have high voltage chamber and low voltage chamber switchgear, equipped with high-voltage buses, such as power plants, etc., some of them also have low cycle load shedding for main equipments. The main function of switchgear (switchgear) is to open, control and protect electrical equipment in the process of generation, transmission, distribution and electric energy conversion in power system. The components in the switchgear are mainly composed of circuit breakers, isolation switches, load switches, operating mechanisms, mutual inductors and various protective devices. Many classification methods such as switch cabinet, the circuit breaker installation can be divided into movable switch cabinet and fixed type switch cabinet or cabinet; according to the different structure, can be divided into open type switch cabinet, metal enclosed switch cabinet, and metal enclosed armoured type switch cabinet; according to the different voltage level can be divided into high pressure switch cabinet, medium voltage switchgear and low-voltage switchgear etc.. It is mainly applied to various occasions such as power plants, substations, petrochemical, metallurgical rolling, light industrial textile, mining and mining enterprises, residential quarters, high-rise buildings and so on.
开关柜 - 分类
Switchgear - Classification
1, low pressure pumping switchgear
2. AC low voltage distribution cabinet
3. Metal armoured shifting switchgear
4, low pressure fixed separation switchgear
5, high voltage capacitor cabinet
6. High voltage switchgear
Classification by voltage level
According to the classification of voltage usually AC1000V and hereinafter referred to as the low voltage switch cabinet (such as PGL, GGD, GCK, GBD, MNS, AC1000V) above is called the high voltage switch cabinet (such as GG-1A, XGN15, KYN48), sometimes the voltage of the high-voltage cabinet for AC10kV called the MV Switchgear (such as XGN15 10kV ring network cabinet).
Classification by voltage waveform
It is divided into: AC switch cabinet and DC switch cabinet.
Classification according to internal structure
Extractable switchgear (such as GCS, GCK, MNS, etc.), fixed switchgear (such as GGD, etc.)
Classification by use
The line cabinet, the outlet cabinet, the metering cabinet, the compensation cabinet (capacitance cabinet), the corner cabinet and the bus bar.
