Abstract
The utility model discloses a 20KV high voltage switch cabinet comprising a cabinet body. The internal space of the cabinet body is divided into a bus chamber, a breaker chamber, a mutual inductor chamber and a relay chamber by a baffle plate; the bus chamber is provided with a bus and a current mutual inductor; the breaker chamber is provided with a breaker and a breaker secondary plug; the mutual inductor chamber is provided with a voltage mutual inductor, a cable, a grounding switch and a lightning arrester; the relay chamber is provided with a relay, an ampere meter and a voltmeter; a static contact at the upper end of the breaker is connected with the bus, a static contact at the lower end of the breaker is connected with the voltage mutual inductor and then is respectively connected with the cable, the grounding switch and the lightning arrester; and the relay, the ampere meter and the voltmeter are respectively connected with the breaker secondary plug, the current mutual inductor and the voltage mutual inductor. The 20KV high voltage switch cabinet has small volume, reasonable layout of the internal space of the cabinet body and electric parts, low power consumption, convenient use and maintenance, safety and reliability.
Description
Technical field
The utility model belongs to electric power network equipment, specifically a kind of 20KV high-tension switch cabinet.
Background technology
The high-tension switch cabinet owner will be used for power plant, power transformation the switchgear house acceptance and the usefulness of distributing electric energy of industrial and mining enterprises in one's power, can realize control, protection and detection to circuit.According to simplifying electric pressure, reduce the transformation level, optimize the principle of network configuration, at the load density height, the newly developed area that supply district is big will gradually adopt the power supply of 20KV electric pressure.The shortcoming of prior art high-tension switch cabinet is, volume is big, it is many to take up an area of, box house space and electric component layout are unreasonable, power consumption height, Operation and Maintenance inconvenience, poor stability.The 20KV high-tension switch cabinet, also desirable without comparison product.
Summary of the invention
The purpose of this utility model is to overcome the defective that exists in the prior art, provides that a kind of volume is little, box house space and electric component be rationally distributed, low in energy consumption, and working service is convenient, safe and reliable 20KV high-tension switch cabinet.
The purpose of this utility model is achieved in that a kind of 20KV high-tension switch cabinet, and it comprises casing, and the box house space is divided into bus-bar room, breaker chamber, instrument transformer chamber, relay bungalow by dividing plate; At bus-bar room bus and current transformer are set, circuit breaker and circuit breaker secondary plug are installed, voltage transformer, cable, earthed switch and lightning arrester are set, relay, ammeter, voltmeter are set at relay bungalow in the instrument transformer chamber at breaker chamber; The upper end fixed contact of circuit breaker is connected with bus, the lower end fixed contact of circuit breaker be connected with cable, earthed switch and lightning arrester respectively after voltage transformer is connected; Relay, ammeter and voltmeter are connected with circuit breaker secondary plug, current transformer and voltage transformer respectively.
Described relay bungalow also is provided with thermostat, thermostat respectively with bus, busbar joint on set bus temperature in the corresponding connection of thread detector.
Maintenance for convenience and maintenance are provided with venting closure, bus top cover and outlet chamber top cover on casing; In the front of casing the relay bungalow door is set, breaker chamber door and instrument transformer chamber door; Bus-bar room bonnet and instrument transformer chamber bonnet are set in the back of casing.
The utlity model has following advantage: box house of the present utility model space is divided into bus-bar room, breaker chamber, instrument transformer chamber, relay bungalow by dividing plate, and is relatively independent between each chamber, avoids an isolation ward accident to occur and involve adjacent compartments.Tank material can adopt aluminizing zine plate compacting to form, and assembles firm attractive in appearancely, and floor space is little.Each electric component is rationally distributed, and is easy and safe to operate reliable, satisfies the distribution requirement of 20KV electrical network fully.
