Head wave opening and breaking type quick switch cabinet

Abstract

The invention discloses a head wave opening and breaking type quick switch cabinet. The head wave opening and breaking type quick switch cabinet comprises a quick circuit breaker, a current transformer, a voltage transformer, a voltage transformer fuse, an electrified display and a ground switch; the quick circuit breaker is connected to the current transformer; the current transformer is respectively connected to the voltage transformer fuse, the electrified display and the ground switch; the voltage transformer fuse, the electrified display and the ground switch are connected in parallel; and then, the voltage transformer fuse is connected to the voltage transformer. By means of the head wave opening and breaking type quick switch cabinet disclosed by the invention, quick isolation of internal and external faults of the system can be realized within 20ms; the purpose of governing interference electricity is achieved; and, even if there is no interference electricity governing requirement, the cost of a cable and the switch cabinet also can be saved by about 50%.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a first-wave breaking fast switch cabinet. Background technique [0002] At present, with the rapid development of the economy, people's demand for energy is increasing day by day. The construction of power distribution facilities such as power plants and substations has made the intelligentization of switchgear an indispensable demand. However, the general switchgear , not only the structure is complicated, but also the running status cannot be displayed in a timely and effective manner, which greatly increases the difficulty of operation. At the same time, the employees do not have a high degree of identification when operating, which is very easy to cause failures, and it is impossible to avoid non-professionals. Proper operation, when the switchgear is working, the temperature and humidity will greatly affect its working performance, and even cause safety acciden...

[0002] At present, with the rapid development of the economy, people's demand for energy is increasing day by day. The construction of power distribution facilities such as power plants and substations has made the intelligentization of switchgear an indispensable demand. However, the general switchgear , not only the structure is complicated, but also the running status cannot be displayed in a timely and effective manner, which greatly increases the difficulty of operation. At the same time, the employees do not have a high degree of identification when operating, which is very easy to cause failures, and it is impossible to avoid non-professionals. Proper operation, when the switchgear is working, the temperature and humidity will greatly affect its working performance, and even cause safety accidents, and the switchgear needs to have a lot of functions, and a large number of devices make it difficult for the switchgear to transfer the working data Once presented, it increases the difficulty of detection and maintenance, so it is difficult to adapt to the current market demand
