产品概述 Product Overview
本公司生产的SCB10-18干式电力变压器,树脂混合材料采用搅拌方法和真空薄膜脱气两种技术,使混合料搅拌均匀并排除混合料内的气泡。产品仅有极低的局部放电量,可控制在5PC以下。高、低压线圈均在真空和压力下浇注,使树脂绝缘既具有全包封性,又具有层匝间浸渍性。浇注体具有致密的固化结构,阻然、防爆、不污染环境。通过RS485串行接口与计算机相连,可以集中监视和控制。由于我公司干式变压器具有以上特点,因此广泛应用于输变电系统,如宾馆饭店、机场、高层建筑、商业中心、住宅小区等重要场所,以及地铁、冶金、电厂、轮船、海洋钻井平台等环境恶劣场所。
The SCB10-18 dry-type power transformer produced by our company uses two techniques for the resin mixture material: mixing method and vacuum film degassing, to evenly mix the mixture and eliminate bubbles inside the mixture. The product has an extremely low partial discharge capacity, which can be controlled below 5PC. Both high and low voltage coils are cast under vacuum and pressure, making the resin insulation both fully encapsulated and impregnated between turns. The casting body has a dense solidification structure, which is flame retardant, explosion-proof, and does not pollute the environment. Connected to a computer via RS485 serial interface, centralized monitoring and control can be achieved. Due to the above characteristics of our company's dry-type transformers, they are widely used in power transmission and transformation systems, such as important places like hotels, restaurants, airports, high-rise buildings, commercial centers, residential communities, as well as harsh environments like subways,metallurgy, power plants, ships, and offshore drilling platforms

主要用途 Main Purpose
随着各种变流装置、变频器、电弧炉及其它非线性电气设备大量使用,其谐波电流往往超过国家相关标准的允许数值,严重影响电网的电能质量。
SY-TAL高压滤波成套装置为“无源型”滤波装置,即有滤波电抗器和高压滤波电容器适当组合,精确调谐后使滤波支路对各高次谐波形成低阻抗通道,使相应的谐波电流大部分流入滤波器,以达到滤除谐波电流,使公共接入点谐波电压畸变率减小的目的,除此之外,还提供无功补偿,提高功率因数的作用。
本装置主要安装在6kV、10kV、24kV、35kV、110kV母线侧,适用于电力系统、冶金、钢铁、铝厂、石油、化工、电气化铁路、造纸、造船等谐波电流大的场所。
With the widespread use of various converters, frequency converters, electric arc furnaces, and other nonlinear electrical equipment, their harmonic currents often exceed the allowable values of relevant national standards, seriously affecting the power quality of the power grid.
The SY-TAL high-voltage filtering complete set device is a "passive" filtering device, which consists of a filtering reactor and a high-voltage filtering capacitor appropriately combined. After precise tuning, the filtering branch forms a low impedance channel for each high-order harmonic, allowing most of the corresponding harmonic current to flow into the filter, in order to filter out harmonic current and reduce the distortion rate of harmonic voltage at the common access point. In addition, it also provides reactive power compensation and improves power factor.
This device is mainly installed on the side of 6kV, 10kV, 24kV, 35kV, and 110kV busbars, and is suitable for places with high harmonic currents such as power systems, metallurgy, steel, aluminum plants, petroleum, chemical, electrified railways, papermaking, shipbuilding, etc.

消弧柜 Arc suppression cabinet
产品概述 Product Overview
手车式消弧柜、手车式消弧消谐柜、中置式手车消弧柜、KYN28消弧柜手车手车是开关柜的核心部件,用钢板弯焊接成,底部装有四只滚轮,能水平方向移动,还装有接地触头,导向装置,锁定机构及手车进出手摇机构装置。手车内设有-限流熔断器XRNT1-永磁接触器JZC-电压互感器-JDZJ-REL-RZL-互感器保护熔断器XRNP1-组合式过电压保护TBP-1O,是我公司自主研发产品,随着我国对城市及农村电网的大规模技术改造,城市、农村的配电网必定向电缆化发展,系统对地电容电流在逐渐增大,弧光接地过电压问题也日益严重起来。为了解决上述问题,不少电网采用了谐振接地方式,即在电网中性点装设消弧线圈,当系统发生单相弧光接地时,利用消弧线圈产生的感性电流对故障点电容电流进行补偿,使流经故障点残流减小,从而达到自然熄弧。运行经验表明,虽然消弧线圈对抑制间歇性弧光接地过电压有一定作用,但在使用中也发现消弧线圈存在的一些问题:
由于电网运行方式的多样化及弧光接地点的随机性,消弧线圈要对电容电流进行有效补偿确有难度,且消弧线圈仅仅补偿了工频电容电流,而实际通过接地点的电流不仅有工频电容电流,而且包含大量的高频电流及阻性电流,严重时仅高频电流及阻性电流就可以维持电弧的持续燃烧。
当电网发生断线、非全相、同杆线路的电容耦合等非接地故障,使电网的不对称电压升高,可能导致消弧线圈的自动调节控制器误判电网发生接地而动作,这时将会在电网中产生很高的中性点位移电压,造成系统中一相或两相电压升高很多,以致损坏电网中的其它设备。
Handcart arc suppression cabinet, handcart arc suppression harmonic suppression cabinet, mid mounted handcart arc suppression cabinet, KYN28 arc suppression cabinet. The handcart is the core component of the switchgear, welded with steel plates, and equipped with four rollers at the bottom that can move horizontally. It is also equipped with grounding contacts, guiding devices, locking mechanisms, and handcart entry and exit hand cranking mechanisms. The handcart is equipped with a current limiting fuse XRNT1 permanent magnet contactor JZC voltage transformer JZJ-REL-RZL transformer protection fuse XRNP1 combined overvoltage protection TBP-1O, which is a product independently developed by our company. With the large-scale technological transformation of urban and rural power grids in China, the distribution network in urban and rural areas must be developed towards cable, and the system's ground capacitance current is gradually increasing. The problem of arc grounding overvoltage is also becoming increasingly serious. In order to solve the above problems, many power grids adopt resonant grounding method, which installs arc suppression coils at the neutral point of the power grid. When a single-phase arc grounding occurs in the system, the inductive current generated by the arc suppression coil is used to compensate for the capacitive current at the fault point, reducing the residual current flowing through the fault point and achieving natural arc extinguishing. Operating experience has shown that although arc suppression coils have a certain effect on suppressing intermittent arc grounding overvoltage, some problems have also been found in the use of arc suppression coils:
Due to the diversity of power grid operation modes and the randomness of arc grounding points, it is difficult for arc suppression coils to effectively compensate for capacitive currents. Moreover, arc suppression coils only compensate for power frequency capacitive currents, while the actual current passing through the grounding point not only includes power frequency capacitive currents, but also contains a large amount of high-frequency currents and resistive currents. In severe cases, only high-frequency currents and resistive currents can maintain the continuous combustion of the arc.
When the power grid experiences non grounding faults such as disconnection, non full phase, and capacitive coupling of the same pole lines, the asymmetric voltage of the power grid increases, which may cause the automatic adjustment controller of the arc suppression coil to misjudge the grounding of the power grid and take action. At this time, a high neutral point displacement voltage will be generated in the power grid, causing a significant increase in one or two phase voltages in the system, resulting in damage to other equipment in the power grid.
