Abstract
The utility model provides a phase sequence board convenient for installing and using. Multiple pieces of NdFeB novel magnetic material are connected to the top of the phase sequence board. The multiple pieces of NdFeB novel magnetic material connect with the phase sequence board through a connection device. Sequence numbers on the phase sequence board are hollowed to form hollow patterns in an A shape, a B shape, a C shape and an N shape. The technical scheme in the utility model is that the NdFeB novel magnetic material is adopted to connect with the phase sequence board by utilizing good magnetically conductive capability of iron accessories and the NdFeB novel magnetic material adsorbs on the iron accessories of a telegraph pole firmly. The phase sequence board can be installed conveniently and quickly. The phase sequence board convenient for installing and using in the utility model allows electrified operation. Thus, the power off time is shortened, and the reliability of power supply is improved. Wind and airflow can pass through the hollow patterns in the A shape, the B shape, the C shape and the N shape formed by hollowing the sequence numbers on the phase sequence board, thereby reducing resistance generated by the wind and the airflow to the phase sequence board substantially.
Description
Technical field
The utility model relates to a kind of phase sequence board, relates in particular to a kind of phase sequence board of being convenient to install and use.
Background technology
Electric power phase sequence board is sprayed A phase, B phase, C phase, N phase (neutral line) sign with yellow, green, red, Lan Si kind color respectively at present; Be fixed on A phase, B phase, C phase, N phase (neutral line) gold utensil through the securing member on the shaft tower; Make the clear phase sequence of distinguishing every lead of its operating personnel's ability; Prevent misoperation, avoid casualties, line facility, user's electrical equipment and electrical to damage; Reach the purpose of Electrical Safety, safety utilization of electric power.Use when installing, at first need outage, operating personnel climb up electric pole electric power phase sequence board are fixed on the iron on the electric pole then
AnnexOn, being used to distinguish the three phase mains sequence number and the neutral line, this phase sequence board installation method complicated operation takes time and effort, and also needs power operation simultaneously, uses inconvenience, also has certain risk.
Summary of the invention
The purpose of the utility model has been to provide a kind of phase sequence board of being convenient to install and use, and solves traditional phase sequence board complicated problems is installed, and also can avoid the problem of power operation simultaneously.
The utility model is realized like this; It comprises phase sequence board, neodymium iron boron novel magnetic material, magnetic conductive substance connector; The top that it is characterized in that the phase sequence board is connected with some neodymium iron boron novel magnetic materials, through the magnetic conductive substance connector some neodymium iron boron novel magnetic materials is connected with the phase sequence board.
Sequence number hollow out on the described phase sequence board forms A, B, C, the hollow pattern of N shape.
The surface of said magnetic conductive substance connector is connected with the support slot that Open Side Down and is convenient to install.
The technique effect of the utility model is: the technique effect of the utility model is: utilize good magnetic property of iron fitting and neodymium iron boron (NdFeB) novel magnetic magnetism of material can be strong, temperature performance processes, has good resistance to corrosion and toughness preferably after stablizing, need not; Adopt neodymium iron boron (NdFeB) novel magnetic material to be connected with the phase sequence board, neodymium iron boron (NdFeB) novel magnetic material directly is adsorbed on the iron fitting of electric pole simultaneously.Quick and easy for installation, during operation, can hot line job, reduce interruption duration, improve power supply reliability; Sequence number hollow out on the phase sequence board forms A, B, C, the hollow pattern of N shape can pass through wind, air-flow, reduces wind, the air-flow resistance to the generation of phase sequence board greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The utility model is realized like this; The top of phase sequence board 1 connects an end of magnetic conductive substance connector 3, and the other end of magnetic conductive substance connector 3 is connected with some neodymium iron borons (NdFeB) novel magnetic material 2, and described phase sequence board 1 is provided with hollow out font 4 or pattern; The surface of said sequence number board magnetisable material connector is connected with the support slot that Open Side Down.During use; Stretch into an end of insulating rod and to support phase sequence board 1 in the support slot 5; Then the bamboo punt-pole is elevated to the iron fitting on the electric pole, at this moment neodymium iron boron (NdFeB) novel magnetic material 2 can firmly be adsorbed on the iron fitting, so phase sequence board 1 also is fixed; Sequence number hollow out on phase sequence board 1 forms A, B, C, the hollow pattern 4 of N shape can distinguish three phase mains A, B, C phase sequence and neutral line N, reduces the resistance that wind, air-flow produce phase sequence board 1 simultaneously greatly.
