The LDJK-10 open type (split type) current transformer uses high-quality imported silicon steel sheets with high magnetic permeability as the magnetic material, which has the characteristics of divisible core and low magnetic circuit loss. Its semi-circular core and secondary winding are vacuum cast with high-quality epoxy resin in a flame-retardant plastic shell, which is moisture-proof, stable in performance, and does not require maintenance.

When installing the LDJK-10 open type current transformer, two semi-circular rings are clamped onto the phase separated cable and held tightly with clamps. They are integrated with the cable in a harmonious and beautiful manner, and can be used for 10kV and 35kV cables ranging from 35mm2 to 400mm2. The clamps are made of stainless steel.

Meaning of LFZB1 series high-voltage current transformer models

Structure Introduction
The LFZB1 series high-voltage current transformer is a fully enclosed structure, with an iron core made of excellent magnetic conductive material. The primary and secondary windings, as well as the iron core, are all cast in epoxy resin, which has excellent insulation performance and moisture resistance, and is easy to maintain on the surface. The primary output lines P1 and P2 are located on both sides of the casting body, and the secondary winding output end is in the middle of the casting body. The first group is the metering winding (0.2S level, 0.2 level), marked as 1S1 and 1S2; the second group is the monitoring winding (0.5 level), marked as 2S1 and 2S2; The third group is the protection level winding (10P level), marked as 3S1 and 3S2. If the customer needs, the accurate level combination can be changed arbitrarily. The transformer is of reduced polarity, and the four M10 copper inserts in the middle are the installation holes for the transformer.

5.2 Use
Before use, the polarity of the secondary winding wiring should be checked to ensure that 1S1, 2S1, and P1 have the same polarity. When the primary current flows into the transformer from P1 and flows out from P2, the secondary current flows out from 1S1 and 2S1, passes through the secondary load, and then flows back to the transformer from 1S2 and 2S2. When there is current in the primary winding during operation, the secondary winding must not be open circuited, otherwise dangerous high voltage may be generated between the terminals of the secondary winding

2026-4-30 12:59:00

The LZBW-10 series current transformer is a dry-type outdoor device suitable for current and energy measurement and relay protection in AC lines with a rated frequency of 50Hz and a rated voltage of 10kV and below.

Structure Introduction

The LZBW-10 type transformer is modified based on the crude oil immersion transformer. The main insulation is made of epoxy resin casting, and the entire transformer body is installed in a box and sealed. The first and second output terminals are respectively led out by insulated porcelain sleeves, and there are four slots on the bottom plate for installation and fixation. According to user needs, when the current is below 200A, a single insulated porcelain sleeve can be used to lead out the primary wire and divide it into P1 and P2 terminals, or two insulated porcelain sleeves can be used to lead out the P1 and P2 terminals. At the same time, when the current is below 200A, it can be made into a dual ratio (such as 75-150/5A). The product not only has the advantages of high temperature resistance, aging resistance, strong antifouling, but also solves the problem of oil leakage of crude oil immersed products.

1.3 Purpose
LZZBJ-10 and LZZB-10 current transformers are indoor, epoxy resin cast, all condition products that have been installed in VE-10 mid mounted switchgear and are also suitable for other switchgear. They are used for current and energy measurement and relay protection in power systems with a rated frequency of 50Hz and a rated voltage of 10KV and below
1.4 Structure Introduction: This model of transformer adopts epoxy resin fully enclosed casting molding. Small size, light weight, suitable for installation in any position and direction, with four M10 screw holes at the bottom for installation.

The iron core of LZZB-10 and LZZBJ-10 current transformers is wound in a circular shape with high-quality cold-rolled silicon steel sheets and undergoes strict heat treatment. The secondary coil consists of two windings: the measurement level and the protection level.

500/5								thirty	seventy-five
600/5								thirty	seventy-five
800/5								forty	one hundred
1000/5								fifty	one hundred and twenty-five

LZZB-10 and LZZBJ-10 current transformers are only suitable for indoor installation, and their installation locations should comply with the following regulations:

2.1 Environmental temperature: maximum+40 ��, minimum -10 ��, daily average temperature not exceeding+30 ��;
2.2 Altitude: not exceeding 1000M;
2.3 Atmospheric conditions: The relative humidity of the air is 100 (20 ��), and there are no gases, vapors, dust, or corrosive or explosive media in the atmosphere that seriously affect the transformer;
2.4 This series of products is a reinforced insulation (full working condition) type, which can operate under humid, condensed, and Class II pollution conditions (with an altitude not exceeding 3000M under Class II pollution conditions alone).

3.1 Maximum operating voltage: 12KV
3.2 Rated frequency: 50Hz
3.3 Rated primary current: 5-1250A
3.4 Rated secondary current: 5A
3.5 Level combination: 0.5/10P, 0.2/10P
The 1-second rated short-time thermal current, rated dynamic stability current, and rated load of the 3.6 transformer are shown in Table 1 and Table 2.

4.1 Installation
The appearance and installation dimensions are shown in Figure 1 and Figure 2. There are four M10 screw holes at the bottom of the product, which are used to fix the product during installation. The surface of the casting body should not be damaged, and the primary terminal should be prevented from bending under mechanical force. When wiring, the protective oil on the contact surface should be wiped off to ensure good contact.
4.2 Use
Before use, check the wiring of the secondary winding. When the primary current flows from P1 to P2, the secondary current flows from 1S1 and 2S1 to 1S2 and 2S2 respectively through the external load. During operation, attention should be paid to the secondary winding not being open circuited, otherwise dangerous high voltage will be generated at the secondary terminal.
3 Maintenance
The casting body of this product does not require special maintenance, only the dust accumulated on the surface of the casting body needs to be regularly removed.
