Cabinet selection scheme

Cabinet's main function is: to ensure normal operation of the equipment in a cabinet put oneself in another's position, not affected by the outside world, and to protect the operator, to avoid dangerous contact. Cabinet is the most direct physical these expensive electric equipment protection. Product density increased as the cabinet inside is disposed, need higher bearing capacity, cabinets to provide good bearing capacity, more should be suitable for heavy duty handling. Bearing has become the basic requirement for a qualified cabinet products. High quality bearing capacity cabinet must be at least more than 1000 kg. To control the cabinet of the industry, if it's just PLC control cabinet, generally the weight of all the equipment is not very big, so 600 kg of bearing capacity is the basic can meet the requirements. For the rack to place in the equipment of large weight ( Such as frequency converter, reactor) Need to consider when installation plate is there enough bearing capacity, plane mounted with heavy rail installation set up when necessary.
cabinets need to be installed outside, insist on IP protection level is higher, can also give cabinets with canopy. Also need to be considered for corrosion resistance, uv protection.
at the beach or port to use, or used in the industries of petrochemical industry, water treatment, require cabinets have higher corrosion resistance. Cabinet of spraying process has played a vital role.
high quality spray technology on cabinet should have the following features: 1, grease dirt cleaning; 2, m ceramic coating protection, the phosphating technology before, due to the high energy consumption and serious environmental pollution has been eliminated; 3, swimming primer, enhance the corrosion resistant ability of plank; 4, at the end of the spray provide good protection. By spraying cabinet process and related corrosion resistance, salt fog test, can guarantee the ark with high anti-corrosion ability.
a lot of electrical equipment within the cabinet because of the heat coming from the operation and can accumulate in the cabinet, after more than a certain degree will affect the normal operation of the equipment, so need to temperature control device in the cabinet. If the cabinet inside and outside temperature difference is bigger, can use the fan heat dissipation; If calorific value contained in the large or enclosure outside temperature difference is small, you can use cooling water heat exchanger; Requiring high temperature stability, can be used to ark cabinet air conditioning refrigeration, cabinet air conditioning does not rely on the external environment temperature, and air conditioning inside and outside circulation were independent of each other, won't destroy the protective effect of the cabinet. In a cold environment, then you need to add heater and thermostat.
in different environment, the procurement of cabinet should have corresponding changes, not all types of rack is suitable for every environment, so there will be no outdoor cabinet.
